Answer:

b. -1%

Explanation:

Expected Alpha = E[rs] - [rf+ B(rm- rf)]. Where rf+ B(rm- rf) is the CAPM return, rf= risk free return, B = Beta of security, rm= return of market, E[rs]= Expected return of security

Expected Alpha = 8% - [3%+1.2*(8%-3%)

Expected Alpha = 8% - 9%

Expected Alpha = -1%

So, the expected alpha for Taggart Transcontinental is closest to -1%.
