The correct option is B Set of points common to any 2 parallel lines
Option A: Set of integers greater than 100 = {101, 102, - - - -}. This is an infinite set as numbers greater than 100 are not countable.
Option B: There are no points common to any 2 parallel lines = { }. This is an empty set with zero elements; thus, it is a finite set.
Option C : There are infinite points on a line. So, this is also an infinite set.
Option D : There are infinite rational numbers between any two rational numbers. Thus, the set of rational numbers between 1 and 2 has uncountable number of elements. Thus, it is also an infinite set.
