Explanation

Let's analyze the options for blank (E) in the sentence: "Among the most significant developments in cell biology is the study of HeLa cells, a line of human cells (E)_ from Henrietta Lacks in 1951." (a) Taken • Meaning in English: Acquired or removed from a source. • Meaning in Hindi: दलया गया। • Correct or Incorrect: Correct. "Taken" fits the context because HeLa cells were physically obtained from Henrietta Lacks in 1951. This accurately describes how the cells were collected. (b) Thought • Meaning in English: Believed or considered. • Meaning in Hindi: सोचा गया। • Correct or Incorrect: Incorrect. "Thought" relates to the process of thinking, which is irrelevant to thephysical action of obtaining cells. (c) Took • Meaning in English: Past tense of "take," meaning to remove or acquire something. • Meaning in Hindi: दलया। • Correct or Incorrect: Incorrect. "Took" is past tense and grammatically incorrect in this sentence structure, as "taken" (past participle) is the appropriate form after "cells were." (d) Sunk • Meaning in English: Past tense of "sink," meaning to descend or go down. • Meaning in Hindi: डबा हुआ। • Correct or Incorrect: Incorrect. "Sunk" has no relevance in the context of acquiring or obtaining cells. (e) Reflected • Meaning in English: To show an image or thought, or to mirror. • Meaning in Hindi: पररलदित या प्रदतदबूंदबत दकया। • Correct or Incorrect: Incorrect. "Reflected" refers to mirroring or representing something, which doesn't fit the context of acquiring cells for research. Final Answer: The most appropriate word for blank (E) is (a) taken.
