You can find out the most efficient portfolio by dividing the expected return by risk deviation that is, you can compute their per unit risk (deviation) return, higher the return per unit risk, the more efficient is:
Portfolio A: 13/18=0.722 per unit risk (deviation)
Portfolio B: 28/23=1.22 per unit risk (deviation)
Portfolio C: 20/18 = 1.11 per unit risk (deviation0
Hence, portfolio B is most efficient
