The word abundant refers to something that is plentiful or existing in large quantities. To find the opposite, we need a word that conveys the idea of scarcity or a small amount.
Consider the meanings of the options:
Short: Generally refers to length or duration, not directly related to quantity.
Limited: Implies restriction or a finite amount, which is closer to the opposite of abundant.
Petty: Typically describes something of little importance or minor; it does not directly relate to quantity.
Meagre: Refers to something that is lacking in quantity or quality, very closely aligning with the idea of scarcity.
Thus, both limited and meagre suggest a lack of abundance, but meagre specifically emphasizes small quantity, making it a strong candidate for the opposite of abundant.
