The answer is D. Chordata.
There are three domains of life - Archaea, Bacteria, and
Eukarya. All organisms that belong to the domains Archaea or
Bacteria have cell walls. In the domain Eukarya, there are some groups
that have cell walls and others that do not.
Chordata is phylum of the kingdom Animalia which belongs to the domain Eukarya. So, Chordata cannot be a domain.
Insertion or

of genes to produce desired proteins.
In the first cross one of the parent has only dominant allele and one has only recessive allele that means the offspring in F1 will be 100% heterozygous

In the black-scholes option pricing model, an increase in the risk-free rate (rfr) will cause an increase in call value and a decrease in put value.
The Black-Scholes Pricing Model for Options is a method for calculating the theoretical value of a call or put option based on six factors: volatility, option type, price of the underlying stock, time value, strike price, and current risk-free rate.
Given that call options have a positive Rho, they typically increase in price significantly as interest rates rise. Due to its negative Rho, put options tend to lose some of their value as interest rates rise, all other things being equal.
Therefore, In the black-scholes option pricing model, an increase in the risk-free rate (rfr) will cause an increase in call value and a decrease in put value.
