The correct answer is Option (4) → The old watchman still remembers being garlanded by the Collector at the Republic Day function in 1998.

Passive of an -ing form after “remember”:

Change	Active	Passive	Why
Main verb kept	still remembers	still remembers	“Still remembers” does not change, because the watchman is still the one remembering. Only the garlanding part changes to the passive.
-ing form made passive	the Collector garlanding him	being garlanded	“Him” is the watchman, who is already the subject, so it drops out. “Garlanding” becomes being + past participle (V3): “being garlanded”.
Agent (by ...)	the Collector	by the Collector	The Collector is named, so the doer comes after “by”.
Full sentence	The old watchman still remembers the Collector garlanding him at the Republic Day function in 1998.	The old watchman still remembers being garlanded by the Collector at the Republic Day function in 1998.

Other verbs followed by an -ing form work the same way, like hate, avoid and mind. Example: Rahul hates people calling him by his nickname. → Rahul hates being called by his nickname.

Why the Other Options are Incorrect?

Option 1: The old watchman still remembers to be garlanded by the Collector at the Republic Day function in 1998. — Incorrect. After “remember”, “to be garlanded” points to something still to happen later. It cannot go with an event of 1998.

Option 2: The old watchman still remembers having garlanded the Collector at the Republic Day function in 1998. — Incorrect. This turns the meaning around. Now the watchman put the garland on the Collector.

Option 3: The old watchman is still remembered for being garlanded by the Collector at the Republic Day function in 1998. — Incorrect. “Is still remembered” makes the watchman the one whom others remember. In the given sentence, he is the one who remembers.
