In a corequisite constraint, what must happen to the two binary variables involved?

• A. They must both be zero
• B. They must both be equal
• C. One must be greater than the other
• D. One must equal two

Answer: (B)

In a corequisite constraint involving two binary variables, both variables must represent the same condition, meaning that they must be equal. This equality is essential because a corequisite typically implies that the occurrence of one variable necessitates the occurrence of another. Thus, if one variable is '1' (or true), then the other must also be '1' to satisfy the constraint, and conversely, if one is '0', the other must also be '0'. This ensures that both conditions are aligned and properly reflect the co-requirement outlined in the corequisite relationship. Hence, the requirement that they are equal captures the essence of this relationship accurately.
