Option (a) is correct.

Explanation:

E (r) = Rf + B (Rm - Rf)

where,

E (r) = Expected return

Rf = risk free rate

B = Beta

Rm = Market Return

Rm = Rf is Market risk premium

11.75% = 5.5% + B (4.75%)

11.75% - 5.5% = B * 4.75%

6.25% : 4.75% = B

B = 1.3157

New required rate of return = Rf + B (Rm - Rf)

= 5.5% + 1.3157 * (4.75% + 2%)

= 5.5% + 1.3157 * 6.75%

= 5.5% + 0.0888

= 0.1438 or 14.38%
