Suppose the statement 'p or a' is true. Of what can you be certain? Explain your reasoning. Choose the correct answer below.

A. g is true. An 'or' statement is true if the second proposition is true, and false otherwise.
OB. One or both of the statements are true. An 'or' statement is true if either or both propositions are true, and false only if both propositions are false.

C. One or both of the statements are true. In an 'or' statement, at least one of the propositions is always true.

D. q is true. In an 'or' statement, the first proposition is false, so the second proposition, q, must be true.

E. p is true. An 'or' statement is true if the first proposition is true, and false otherwise.

F. D is true. In an 'or' statement, the second proposition is false, so the first proposition, p, must be true.
