Which one of the followings is most correct? (a) Select B as its BC ratio is the largest among the three alternatives. (b) Select C as its incremental BC ratio over either A or B exceeds 1. (c) Select A as it requires the least investment and recurring annul cost. (d) Select B as its incremental BC ratio over A exceeds 1
