A) Vacuously
B) Trivially
C) Directly
D) Indirectly

B) Trivially

In trivial truth, the second statement should be true, whatever the first statement is. In this case, The first statement is that, "Whenever I eat meat I feel great". This statement could be true or false it doesn't matter. The second statement "Later, you discover that I'm a vegetarian" is true. The second statement is true as he knows the fact later that he is vegetarian. The second statement that, I am vegetarian, does not means that he cannot eat meat.

So this is the reason, if second statement is true it means that it is trivially proposition.
