Crux of the question - "but" is used to join two independent clauses

The part before "but" is an independent clause, hence the part of thr sentence after "but" has to be an independent clause - subject + verb

A. but rarely
- lacks a subject.
- acknowledged acts as a modifier in absence of a helping verb

B. was rarely
- the part before underlined portion is an independent clause. In absence of "FANBOYS", the structure joins to IC with comma - wrong

- As mentioned in choice 1 analysis, this structure lacks a subject.
- in addition to that, present perfect tense is not required and does not make sense

- "which" refers to the noun before comma - multi-jet rockets - such a reference completely distorts the meaning of the sentence.

E. but he was rarely
- "but" is used for connecting two independent clauses
- presence of a subject "he" - correct
- "was acknowledged" - correct tense
