Correct answer. There are no errors in this formation.B. is usually regarded as making way through history by staggers and strides
The sentence talks about what is happening in "history". Therefore, we need to use the past tense or present perfect tense ("having made") rather than present tense ("making way"). Eliminate.C. is regarded usually as making a way through history in staggers and strides
Change in meaning. "Usually" is applicable to "regarded" and not "making way", since, as per the sentence, it has always made a way through history by staggers and strides. Also, the present tense ("making way") usage is incorrect as in (B). Eliminate.D. . is usually regarded as having made way for history in staggers and strides
Change in meaning - "made way for history" means moved away and let history take its place, which is not the meaning conveyed by the sentence. eliminate.E. is regarded usually as having made a way through history by staggering strides.
Incorrect placement of "usually" resulting in change in meaning as in (C). Also, the strides are not "staggering" (an adjective) but staggers is used as a noun. Eliminate.Hope this helps.
