The correct answer for the question that is being presented above is this one: "A. approve international treaties." The role of the Senate in regard to treaties is to approve international treaties. It is the responsibility of the members of the Senate.
The first alternative is correct (A).
The Treaties are negotiated by the executive branch, that is, by the president. The Senate has the power to evaluate the treaties and approve them or not.
It is a constitutional prerogative to moderate the powers of the president and ensure that the interests of the nation are discussed in more than one sphere of power.
