Why the answer is B, and why the others tempt you.
When the Central Bank sells government securities, buyers (commercial banks and the public) pay for them, which reduces the reserves held by commercial banks. With lower reserves, commercial banks have less capacity to extend credit, leading to a contraction in the money supply. This is a contractionary open market operation used to control inflation.
