Option 1 -> The passage doesn't indicate pity as the motivation; the coin was given in response to the beggar's specific reminder about the abhishekam.
Option 2 -> Mother explicitly states "I forgot all about the promised abhishekam. This is a reminder," showing gratitude for the beggar's reminder about the religious ritual.
Option 3 -> Mother was in "hearty agreement" with the beggar's view that the snake represented God Subramanya and shouldn't be killed, showing her pleasure at these views.
Option 4 -> While the beggar asked for alms, the passage makes clear the coin was given as a response to the religious reminder, not general charity.
Hence, Options 2 and 3 -> Mother gave the coin specifically because the beggar reminded her about the forgotten abhishekam (promised ritual) and because she heartily agreed with the beggar's spiritual perspective that the snake was a divine visitation from God Subramanya that shouldn't be harmed -> correct
