ASSERTION (A) : IF TWO LINES AB AND CD INTERSECT AT O SUCH THAT ∠AOC = 40 ° , THEN ∠BOC = 140°.
REASON (R): IF TWO STRAIGHT LINES INTERSECT EACH OTHER THEN VERTICALLY OPPOSITE ANGLES ARE EQUAL
BOTH ASSERTION ( A ) AND REASON ( R ) ARE TRUE AND REASON ( R ) IS THE CORRECT EXPLANATION OF ASSERTION ( A)
BOTH ASSERTION ( A ) AND REASON ( R ) ARE TRUE BUT REASON ( R ) IS NOT A CORRECT EXPLANATION OF ASSERTION ( A)
ASSERTION ( A ) IS TRUE AND REASON ( R ) IS FALSE
ASSERTION ( A) IS FALSE AND REASON ( R ) IS TRUE
