I feel unprepared. Maybe increasing the memory for the NameNode makes sense to handle more files.

True, but that might cause more overhead. Bigger blocks usually mean fewer, larger files.

But isn't decreasing the block size, like in C or F, a viable option? Smaller blocks might help.

I think option D, increasing the memory for the NameNode, seems logical.

Yeah, I'm stuck between increasing the block size or messing with the NameNode settings.
