Operations support systems are generally used by managers at lower levels of an organization. Therefore, the correct answer is option 'D'.
An operational support system (OSS) is a collection of computer programs or information technology (IT) system used by communications service providers to monitor, control, analyze, and manage a computer or telephone network system.
OSS software is designed specifically for telecommunications service providers and is primarily used to support network processes such as network inventory management, network component configuration, service provisioning, and fault management.
With the proliferation of new broadband and Voice over Internet Protocol (VoIP) systems, OSS and network management are increasingly being applied to home networks.
An OSS is also referred to as a business support system (BSS).
Hence, the correct option is 'D'.

Answer:
1.15
Explanation:
If investment is made in equal proportions, it means that;
weight in risk free ; wRF = 33.33% or 0.3333
Let the stocks be A and B
weight in stock A ; wA = 33.33% or 0.3333
weight in stock B; wB = 33.33% or 0.3333
Beta of A; bA = 1.85
Let the beta of the other stock be represented by "bB"
Beta of risk free; bRF = 0
Beta of portfolio = 1 since it is mentioned that "the total portfolio is equally as risky as the market "
The weight of portfolio is equal to the sum of the weighted average beta of the three assets. The formula is as follows;
wP = wAbA + wBbB + wRF bRF
1 = (0.3333 * 1.85) + (0.3333*bB) + (0.3333 *0)
1 = 0.6166 +0.3333bB + 0
1 - 0.6166 = 0.3333bB
0.3834 = 0.3333bB
Next, divide both sides by 0.3333 to solve for bB;
bB = 0.3834/0.3333
w=bB = 1.15
Therefore, the beta for the other stock would be 1.15
