Answer
(d) 12 pairs.
12 PAIRS of cranial nerves arise from the brain.
READ THE OPTIONS CAREFULLY — this question is testing precision, not recall. Both "12" and "12 pairs" are offered, and only the second is correct: the nerves are PAIRED, one of each on either side of the body, so there are 12 pairs and not 12 nerves.
The figures to learn together, because the paper offers both: CRANIAL nerves — 12 pairs, arising from the BRAIN SPINAL nerves — 31 pairs, arising from the SPINAL CORD
Whenever a question offers the same number with and without "pairs", the answer is almost always the one WITH it.
