A
Correct answer
Explanation
The sentence requires the simple past tense to match 'successfully' as an adverb modifying the verb. 'Negotiated' correctly completes the active voice construction 'We successfully negotiated the inclusion of that amendment'. 'Had negotiated' (past perfect) would require another past event for sequencing, while 'being negotiated' and 'negotiating' would need auxiliary verbs like 'are/were' to be grammatical.
