In the following options lettered A to D, all the words except one have the same stress pattern. Identify the one with the different stress pattern.

Analyzing the question: We need to find the word whose stress falls on a different syllable from the others.

Concept: In English, stress is the syllable said with more force. Marking the stressed syllable for each word:

• important = im-POR-tant (stress on the 2nd syllable)
• rehearsal = re-HEAR-sal (stress on the 2nd syllable)
• implement = IM-ple-ment (stress on the 1st syllable). As a noun or verb, "implement" is stressed on the first syllable.
• condition = con-DI-tion (stress on the 2nd syllable)

Solution: Three words (important, rehearsal, condition) are stressed on the second syllable. Only "implement" is stressed on the first syllable.

So the odd one out is **C.

Tip: Many words ending in -tion, -sal, or -tant take stress on the syllable just before the ending (con-DI-tion, re-HEAR-sal, im-POR-tant). Words ending in -ment often keep stress early (IM-ple-ment, GOV-ern-ment, MOV-ment). Always say the words aloud and listen to where your voice naturally pushes harder.
