Topic: বানান শুদ্ধিকরণ, Subject: Bangla Bengali literature (বাংলা সাহিত্য)

Best Answer Explained in Below-:

The correct answer to the question 'শুদ্ধ বানান কোনটি?' (Which is the correct spelling?) is 'D) পিপীলিকা'. Understanding why this option is correct requires a brief analysis of Bengali phonetics and spelling conventions.

The term 'পিপীলিকা' refers to an ant, and in Bengali, this word is derived from the Sanskrit term 'पिपीलिका' (pipīlikā). In Bengali, the sound of the long vowel "ী" (pronounced "ee") is represented by "ী" following the letter "প" (pa) to denote the proper length of the vowel sound, while the presence of the "লিকা" (likā) ending denotes the noun form.

Option A) 'পিপিলিকা' is incorrect because it suggests a short vowel sound which alters the pronunciation. Option B) 'পীপিলিকা' introduces an unnecessary lengthening of the first vowel sound, which is not correct. Option C) 'পিপিলীকা' similarly misrepresents the vowels' lengths.

Therefore, 'D) পিপীলিকা' is the correct answer as it accurately reflects the required long vowel sound typical in the standard pronunciation of the word while adhering to Bengali orthographic norms, ensuring both its etymological accuracy and phonetic clarity.
