How is the answer option C?

#1

I executed the program after the quiz in the IDE and it gave me a very long value with max_size() function which seemed to be the available space in memory and not equal to 10^1. Please clear my doubt.

@rahul.maheshmaheshwari
since we are using the operation (x % 10) < (y % 10)
and set can only take non duplicate values
anything mod 10 would give answer b/w 0-9 so permissible answers would give a get of max 10
