Answer 1

Answer:

D. Seldom had good marks been obtained by those who worked hard.

Seldom had good marks been obtained by those who worked hard - This option correctly uses the passive voice and the past perfect tense ("had been obtained"), which matches the past tense of the original sentence ("worked"). It also conveys the intended meaning that obtaining good marks was rare for those who worked hard.
