In this spelling based English question, four different spellings of a word are given. Select the correctly spelt form of the word that means "very strange or unusual".

Introduction / Context:
This question tests your knowledge of correct English spelling. You are given several variants of a word that means "very strange or unusual" and must pick the correct form. Spelling questions are common in competitive exams because they quickly show how familiar you are with standard written English. The word being tested here is commonly used in descriptions of unusual events, behaviour, or appearances.

Given Data / Assumptions:

- The intended word means "very strange or unusual". - Options: Beizarre, Bizaarre, Bizarre, Bigarre, Bizzarre. - Only one spelling matches standard dictionary English.

Concept / Approach:
The correct spelling of the word is "bizarre". It comes from French and is spelled B I Z A R R E. Many misspellings arise when people misplace the vowels or double the wrong consonants. To solve such questions, it helps to visualise the word as you have seen it in books or articles and to recall that only the final consonant "r" is doubled, with a single "z" at the start and the vowel pattern "i" then "a".

Step-by-Step Solution:

Verification / Alternative check:
You can mentally place the word in a simple sentence to help visual memory. For example: "The magician performed a bizarre trick." When you picture this sentence as it often appears in books or online articles, the image of "bizarre" with one "z" and two "r" letters is very familiar. None of the alternative spellings look natural in that context, which confirms that option C is correct.

Why Other Options Are Wrong:
"Beizarre" introduces an incorrect "ei" sequence at the beginning. "Bizaarre" uses too many vowels and consonants in the ending, resulting in a non standard form. "Bigarre" uses the letter "g" instead of "z", completely changing the word. "Bizzarre" doubles the wrong consonant, giving "zz" instead of the correct "rr" structure. Since standard English spelling is fixed for common words, any deviation from "bizarre" is considered incorrect.

Common Pitfalls:
Learners often confuse the patterns of double consonants in words borrowed from other languages. Many think that because the sound is strong at the start, the "z" must be doubled, but in "bizarre" it is the "r" that is doubled. Others get misled by similar looking words in their own language. A good habit is to read widely and notice standard spellings of frequently used descriptive words. Over time this creates a mental dictionary that makes such questions much easier.

Final Answer:
The correctly spelt word is "Bizarre", so the correct answer is Bizarre.
