Answer:

A. 0%

Explanation:

The expected rate of return of A = 11%

Expected rate of return of B = 7%

Risk free rate = rfr = 5%

Sdb = 3%

SDa = 18%

Correlation coefficient = 0.50

The formula used to solve for the required answer is in the attachment.

When computed, we have

0.000054-0.000054/0.000036+0.000216

= 0/0.000252

= 0

Therefore the first option is the correct answer

0% should be invested in stock A.
