Answer:
In employment law, a bona fide occupational qualification (BFOQ) (US) or bona fide occupational requirement (BFOR) (Canada) or genuine occupational qualification (GOQ) (UK) is a quality or an attribute that employers are allowed to consider when making decisions on the hiring and retention of employees—a quality that when considered in other contexts would constitute discrimination and thus be in violation of civil rights employment law. Such qualifications must be listed in the employment offering.[citation needed]
Explanation:
Canada
The law of Canada regarding bona fide occupational requirements was considered in a 1985 Canadian court case involving an employee of the Canadian National Railway, K. S. Bhinder, a Sikh whose religion required that he wear a turban, lost his challenge of the CNR policy that required him to wear a hard hat.[1] In 1990, in deciding another case, the Supreme Court of Canada amended the Bhinder decision: "An employer that has not adopted a policy with respect to accommodation and cannot otherwise satisfy the trier of fact that individual accommodation would result in undue hardship will be required to justify his conduct with respect to the individual complainant. Even then the employer can invoke the BFOQ defence."[2]
United States
In employment discrimination law in the United States, both Title VII of the Civil Rights Act of 1964 and the Age Discrimination in Employment Act contain a BFOQ defense. The BFOQ provision of Title VII provides that:
[I]t shall not be an unlawful employment practice for an employer to hire and employ employees, for an employment agency to classify, or refer for employment any individual, for a labor organization to classify its membership or to classify or refer for employment any individual, or for an employer, labor organization, or joint labor-management committee controlling apprenticeship or other training or retraining programs to admit or employ any individual in any such program, on the basis of his religion, sex, or national origin in those certain instances where religion, sex, or national origin is a bona fide occupational qualification reasonably necessary to the normal operation of that particular business or enterprise ...[3]

Answer: C
Explanation:
This is because although the coupon rate is devoid of federal income tax any market discount is taxed as interest income earned. So so if there is a way that they can be taxed without jeopardizing their basic Federal income tax-free status, why not? The discount can be accreted annually and tax paid, or the tax can be paid at maturity or sale date.
 
        
                    
             
        
        
        
Answer: 45%
Explanation:
Standard deviation for the portfolio will be a weighted average of the standard deviations of the individual assets. 
Risky asset has standard deviation of 20%. Assume the weight is x. 
Treasury bills have a standard deviation of 0 as they have no risk. Assume their weight is y. 
Target Standard deviation is 9%. 
Formula would be:
9% = (x * 20%) + (y * 0%)
20%x = 9%
x = 9% / 20%
x = 45%
