B
Correct answer
Explanation
This is a homophone pun: 'night-mare' (a scary dream) sounds like 'nightmare' (a horse ridden at night). The humor comes from the double meaning - a mare (female horse) ridden at night versus a bad dream. 'Horses do not like so' and 'race horse' are too literal, while 'old horse' is irrelevant.
