Answer:
The correct answer and the meter used by William Blake in "The Lamb" is D. trochaic tetrameter,
Explanation:
The poem replicates the rhyme scheme and meter of an hymn, thus the use of trochaic meter. This pattern is standard in hymns, but less common in poetry as a whole. The rhythmic pattern of a trochee repeats the pattern of a stressed beat followed by an unstressed beat.
These patterns make it easier to remember hymns, but also reflect the air of nursery rhyme he wanted to convey in "The Lamb".
