In the following question, four English words are given. Out of these four, select the word that is incorrectly spelt.

Introduction / Context:
This spelling question tests your knowledge of standard English spellings for relatively advanced vocabulary. Competitive exams often include one incorrectly spelt word among three correctly spelt ones. Your task is to recognise which word does not match the correct dictionary spelling, even if it looks similar at first glance.

Given Data / Assumptions:

• Four options are given: Acquiescence, Alienate, Belligerent, Sabbotage.
• Exactly one of these four words is spelt incorrectly.
• All words are common in formal English, media, and academic writing.
• We must identify the incorrect spelling, not the meaning or usage.

Concept / Approach:
The fastest strategy is to recall or mentally visualise how these words normally appear in printed text, textbooks, or dictionaries. Acquiescence is the noun from acquiesce. Alienate means to make someone feel isolated. Belligerent describes an aggressive or warlike attitude. The word referring to deliberate damage or destruction of property is correctly spelt sabotage, not sabbotage. Double consonants often create confusion, so questions are designed around such traps.

Step-by-Step Solution:
Check Acquiescence: standard spelling is A C Q U I E S C E N C E, which matches option A.Check Alienate: standard spelling is A L I E N A T E, which matches option B.Check Belligerent: standard spelling is B E L L I G E R E N T, which matches option C.Check Sabbotage: the correct spelling is S A B O T A G E with a single b. The double b in Sabbotage is incorrect.Therefore Sabbotage is the incorrectly spelt word and must be selected.

Verification / Alternative check:
If you are unsure, break the confusing word into parts. Sabotage comes from French sabotage and is widely used in security, defence, and business contexts: sabotage of equipment, sabotage of negotiations, and so on. In none of these contexts is a double b used. Searching your memory of newspapers or books will repeatedly show sabotage, not sabbotage.

Why Other Options Are Wrong:
Acquiescence, although long and complex, is correctly spelt. Alienate is a straightforward word that appears exactly as in the dictionary. Belligerent is often used in international relations or behaviour descriptions and is correctly formed with double l and one g in the middle. Since all three are correct spellings, they cannot be chosen as the incorrectly spelt word.

Common Pitfalls:
Examinees sometimes overthink and suspect Acquiescence because it looks complicated, or Belligerent because of its double consonants. However, exam setters deliberately place one very typical misspelling, such as an unnecessary doubled consonant. A careful visual check usually reveals which word looks odd compared to how you have seen it before.

Final Answer:
The incorrectly spelt word is Sabbotage, which should correctly be spelt “sabotage”.
