  1. B and C only
  2. B, D and E only

A: Chordates have a dorsal, hollow and single nerve cord; a mid-dorsal, solid and double nerve cord is not a chordate feature — so statement A is incorrect.

B: Chordates have a closed circulatory system — correct.

C: Paired pharyngeal gill slits are present — correct.

D: The heart of chordates is ventral, not dorsal — incorrect.

E: Chordates are triploblastic and coelomate, not pseudocoelomate — incorrect.

So only B and C are correct.
