Dear Friends,
Here is a detailed explanation to this question-
Choice A: This answer choice maintains proper tense use, conveys the intended meaning of the sentence, and is quite concise. Thus, this answer choice is correct.
Choice B: This answer choice incorrectly uses the past perfect tense to refer to both actions described in the sentence; the ages at which babies begin to open and close their hands and the fact that they continue to develop fine motor skills as they age are universal facts, and statements conveying them must be in the simple present tense. Thus, this answer choice is incorrect.
Choice C: This answer choice is highly awkward due to the use of the passive voice and the use of the gerund phrase "the opening and closing"; this answer choice implies that the opening and closing of babies' hands is an autonomous function that babies do not control. Thus, this answer choice is incorrect.
Choice D: This answer choice incorrectly uses the present continuous tense to refer to a statement of universal truth. Thus, this answer choice is incorrect.
Choice E: This answer choice incorrectly uses the present perfect continuous tense to refer to the statement of universal truths. Thus, this answer choice is incorrect.
Hence, A is the best answer choice.
