This question was previously asked in
SSC CHSL 2025 Tier 1 Question Paper (21-Nov-2025) (Shift 1)
The correct answer is

A hidden ancient tomb has been discovered by the archaeologists after many years of searching.

The active sentence is 'The archaeologists ... have discovered a hidden ancient tomb', whose verb 'have discovered' marks the present perfect tense.

To convert to passive we make the object 'a hidden ancient tomb' the new subject and move the doer 'the archaeologists' into a 'by' phrase.

The passive of the present perfect follows the fixed pattern 'has/have been + past participle', so the tense signal 'have ... -ed' must be preserved, not changed.

The new subject 'a hidden ancient tomb' is singular, so the auxiliary is 'has', giving 'has been discovered' and keeping the original present-perfect meaning.

Option A uses the simple past 'was discovered', option C uses the past perfect 'had been discovered', and option D uses the simple present 'is discovered', so each alters the tense and is rejected.

The adverbial 'after many years of searching' stays put, attached to the action.

Hence, the correct passive form is A hidden ancient tomb has been discovered by the archaeologists after many years of searching.
