It is the second answer choice
The correct answers are B and D.
A is false because, even though it's true that 4 points are not necessarily on the same line, it is not required that they are collinear in order for them to be coplanar.
B is true: two points always lie on the same line (and thus also in infinite same planes), but four points are not always coplanar
C is false. As a counterexample pick the four points (0,0, 0), (1, 0, 0), (0, 1, 0), (0, 0, 1).
D is true: two points are always on the same line, three points always lie in a common plane, but 4 points are not necessarily coplanar.

Step-by-step explanation:
A positive integer is a perfect square if it can be expressed as the product of two same positive integers.
Any number that cannot be written this way is a non-perfect square.
Since the integers are not presented, we will quickly examine the perfect squares between 1 and 50.
The perfect squares are: 1,4,9,16,25,36 and 49.
- 1=1 X 1
- 4=2 X 2
- 9=3 X 3
- 16 =4 X 4
- 25 =5 X 5
- 36 =6 X 6
- 49 =7 X 7
Every other positive integer in the numbers 1-50 apart from those listed above is a non-perfect square.
