There are two main problems with this sentence.
(1) The subject (the first United States Solicitor General) does not have a verb.
(2) The past perfect tense had served is wrong as the phrase earlier in his life makes it clear that his service as a lieutenant occurred before his service as solicitor general. Consequently, the past perfect tense is not needed to differentiate the timing of the two events in the past.

D. the past perfect tense had served is wrong as the phrase earlier in his life makes it clear that his service as a lieutenant occurred before his service as solicitor general
E. the past perfect tense is not used; the subject (the first United States Solicitor General) has a verb
