In a BIP problem, 1 corresponds to a yes decision and 0 to a no decision. If project A can be undertaken only if project B is also undertaken then the following constraint needs to be added to the formulation:
A) A + B ≤ 1.
B) A + B = 1.
C) A ≤ B.
D) B ≤ A.
E) None of the choices is correct.

The constraint A ≤ B ensures that if project A (A=1) is undertaken, then project B (B=1) must also be undertaken, as A cannot be greater than B. This effectively means project A can only proceed if project B does.

In a BIP Problem, 1 Corresponds to a Yes Decision
