Final answer:
The word 'weary' as a verb means to become sleepy or lose energy, hence the matching option is (a) tire. As a noun, 'weary' refers to a vehicle's tire but none of the options given relate to this definition.
Step-by-step explanation:
The word weary has a couple of meanings depending on its usage. As a verb, weary means to become sleepy or lose energy, which is synonymous with option (a) tire. When someone says they are weary, it may imply that they are not just physically tired but also mentally drained. For instance, after a long day of work, one might say, "I am weary from all the meetings."
As a noun, the word weary has an entirely different definition unrelated to the feeling of tiredness—it refers to a ring-shaped rubber component that fits over the wheel of a vehicle, better known as a tire. However, this definition does not match any of the options provided in the question.
