Answer 1

Answer: soft constraint

Step-by-step explanation:

The soft constraint is defined as

• a constraint on a random variable (X)that permits overruling the constraint.

• a function from the domains in its scope(set of variables ) into a real number.

Hence, a constraint which represents a target value for a problem is called a soft constraint.

Thus the correct option is d. soft constraint.
