1. Set of points of a given line is a finite set.
2. Intelligent students in a class is a set.

Which of the above statements is/are not correct?

• A. $1$ only
• B. $2$ and $3$ only
• C. $1$ and $2$ only
• D. $1,2$ and $3$

Answer 1

The correct option is D $1,2$ and $3$

Consider statement $\left(1\right)$. It is false as a line has an infinite number of points.
Consider statement $\left(2\right)$. It is false as word "intelligent" has no specific meaning.
Consider statement $\left(3\right)$. It is false as word "Good" has no specific meaning.
Hence all statements are incorrect.
