Answer 2

Answer:

The correct answer is option (c)

Explanation:

n-queen problem does not exist when n=2 and n=3.

n-queen is a very popular problem in programming where we have to place n number of queens on the chess board in a way so that no two queens attack on each other.

When n =1, the problem has a trivial solution, and  for n =2 and n =3 no solution exists.
