Concept:Stress pattern refers to the syllable in a word that is spoken with the greatest emphasis or force.
Explanation:Every English word with more than one syllable has one syllable that is said more strongly than the others.
Check where the stress falls on each word given in the options.
mountain → MOUN-tain: stress is on the first syllable.
caution → CAU-tion: stress is on the first syllable.
creature → CREA-ture: stress is on the first syllable.
extrude → ex-TRUDE: stress is on the second syllable.
Three of the words follow the first-syllable stress pattern.
Only "extrude" follows a different pattern by placing the stress on the second syllable.
Therefore, the word with a different stress pattern is "extrude".
Answer:B. extrude
