The answer given was C but I think E can be the answer if we use plugging in after combining the statements.

Is b even?

  1. 3a + 4b is even
  2. 3a + 5b is even

if we take b as 0 and a as 2 and combine the two statements then b is not even and we don’t get a definite answer. So how can be the answer C here?
