Answer
Answer: C ✓ checked by 4AB · confidence high
Answer: a–iv, b–i, c–ii, d–iii — code (3).
Explanation
Answer: a–iv, b–i, c–ii, d–iii — code (3) — NaH is a saline (ionic) hydride; BeH₂ is a polymeric chain with 3c-2e bridges; HfH₂.₁ is a non-stoichiometric interstitial hydride; [TcH₉]²⁻ is tricapped trigonal prismatic.
