every moment in the grass was a lion stalking every stillness a lion wait to spring what figure language is it

Answer:
A. Metaphor
Explanation:
"Every movement in the grass was a lion stalking every stillness a lion waiting to spring" is a Metaphor.
A metaphor is a figure of speech which usually refers directly to something by mentioning another. When something is metaphorical, we use it to symbolize another thing.
In the above figurative statement, "every movement" was used to symbolize or infer "the lion's stalking" and "every stillness" symbolizes "a lion waiting to spring".
Therefore, option A is the correct answer.
