A Is the Owner of a Parcel of Land Covered

A is the owner of a parcel of land covered by TCT No. 1. He leased it to B. When sued for ejectment, B contended that A's title is void. Is he correct?

A) Yes, because if A's title is void, he has no right to sue B for ejectment.
B) No, because that is a collateral attack on A's title.
C) Yes, because the decision on the title would be res judicata to the issue of the right to eject A.
D) Yes, because a decision on the title of A is prejudicial to the right to eject B.
