Which of the following words will fit in the given blank (B)?

Explanation

Let's analyze the options for blank (B) in the sentence: "In 1665, Robert Hooke first identified cells while observing cork tissue (B)_ a microscope..." (a) Over • Meaning in English: Positioned higher than something, usually with no contact. • Meaning in Hindi: ऊपर, दबना दकसी सूंपक क क े । • Correct or Incorrect: Incorrect. "Over" suggests a position above something, but without physical connection, which doesn't fit the context of observing through a microscope. (b) Above • Meaning in English: Higher in position, but not in direct contact. • Meaning in Hindi: ऊपर, दबना सूंपक क क े । • Correct or Incorrect: Incorrect. Similar to "over," "above" implies a location higher than something but not touching or interacting with it. It does not work with the idea of using a microscope to observe cells. (c) Under • Meaning in English: Below or beneath something. • Meaning in Hindi: नीचे या दकसी वस्तु क े तले। • Correct or Incorrect: Correct. "Under" is appropriate because cells are observed under a microscope, meaning the tissue is placed beneath the microscope for examination. (d) Below • Meaning in English: Lower than something else in position, but not necessarily directly under. • Meaning in Hindi: नीचे, लेदकन सीधे सूंपक क में नहीूं। • Correct or Incorrect: Incorrect. "Below" does not fit well here, as it generally refers to a relative position, rather than the specific action of using a microscope for observation. (e) Around • Meaning in English: Surrounding something. • Meaning in Hindi: चारोूं ओर। • Correct or Incorrect: Incorrect. "Around" doesn't work in this context, as it suggests surrounding something, which doesn't apply to using a microscope to observe cells. Final Answer: The most appropriate word for blank (B) is (c) under.
