Select the option that best completes the analogy: Enormous : Huge :: Meagre : ?

The relation is a word : a word of the same meaning. Enormous and huge say the same thing, so meagre must be paired with a word meaning the same, which is scanty. 'Ample' is the trap laid for anyone who reads the pattern as opposites, since ample is the opposite of meagre. 'Wealthy' plays on the idea of scarce means, and 'Heavy' is unrelated.
