Answer:The correct answer is A.
Explanation:
Lambic tetrameter (The foot has an unstressed syllable followed by a stressed syllable. This pattern repeats four times in each line).
Twas brillig, and the slithy toves
Did gyre and gimble in the wabe
In the excerpt the first syllable is not stressed, and it is followed by a stressed syllable; this is called a iamb. This was common in Greek comedies and tragedies.
This pattern is repeated four times during the verses, so it is a tetrameter.
