Each question has four choices a, b, c and d, out of which only one is correct. Each question contains STATEMENT 1 and STATEMENT 2.
Both the statements are TRUE and STATEMENT 2 is the correct explanation of STATEMENT1.
Both the statements are TRUE but STATEMENT 2 is NOT the correct explanation of STATEMENT 1.
STATEMENT 1 is TRUE and STATEMENT 2 is FALSE.
STATEMENT 1 is FALSE and STATEMENT 2 is TRUE.
Statement 1: if `A ,B ,C` are the angles of a triangles and `|[1, 1, 1], [ 1+sin A ,1+sinB, 1+sin C], [ sin A+sin^2A, sin B+sin^2B,sin C+sin^2C]|=0` , then triangle may not be equilateral
Statement 2: if any two rows of a determinant are the same, then the value of that determinant is zero.
