The logically equivalent statements are a. (p∨∼q)

Let's analyze the logical equivalence of each statement:

Given

∼(p∨q), which is the negation of (p∨q).

a. (p∨∼q)

This is logically equivalent. De Morgan's Law states that ∼(p∨q) is equivalent to (∼p∧∼q).

b. (∼p∨q)

This is not logically equivalent. It is the negation of (p∨∼q), not ∼(p∨q).

c. (p∧q)

This is not logically equivalent. It is the negation of (p∨q), not ∼(p∨q).

d. (p∨q)

This is not logically equivalent. It is the opposite of ∼(p∨q).

e. (p∧∼q)

This is not logically equivalent. It is the negation of (p∨q), not ∼(p∨q).

f. (p∧q)

This is not logically equivalent. It is the negation of (p∨q), not ∼(p∨q).

Therefore, the logically equivalent statements are:

a. (p∨∼q)
