Correct option is C
Explanation of the Correct Answer: · The active sentence "I shared a clipping" is in past simple tense.
· Passive structure: "A clipping... was shared by me."
· "Was shared" (past simple passive) correctly replaces "shared" (past simple active).
Why Are the Other Options Incorrect? · (a) "Is shared" → Incorrect; wrong tense (present instead of past).
· (b) "Are being shared" → Incorrect; subject-verb agreement error.
· (d) "Are being done" → Incorrect; changes meaning and structure.
Thus, the correct answer is (c) A clipping of myself doing dead-lifting and back squats was shared by me.
