Question

I think B but was told C

Answer 1

check the picture below.

notice 2002, is just a tiny drop from the red line, 2000 is hardly below 2002, so is also close to the red line, and 1998 is also.

now, 1996 is a tad farther than 1998.

to be fair, I'd say 2002, 2001 and 1998, but off all the provided sets, 1998, 2002 and 2000 works.
