A metaphor compares two unlike objects (boots and pig's hooves) without using the words like or as. The second sentence is considered a simile because it uses the word "as" to compare the boots to a pig's hooves.
hi! your answer should be A. "our boots were muddy pig's hooves."
Explanation:
"A."would be the answer because "B."uses the word "as".
A simile is a comparison of two unlike things using the words "like" or "as", therefore B would be a simile and Awould be a metaphor! hope this helps :)
