Consider the lines L1 : r=a+lambdab and ...

Consider the lines `L_1 : r=a+lambdab and L_2 : r=b+mua`, where a and b are non zero and non collinear vectors.
Statement-I `L_1 and L_2` are coplanar and the plane containing these lines passes through origin.
Statement-II `(a-b)cdot(atimesb)=0` and the plane containing `L_1 and L_2` is [r a b]=0 which passe through origin.

A

Statement-I is true, Statement II is also true, Statement-II is the correct explanation of Statement-I.

B

Statement-I is true, Statement-II is also true, Statement-II is not the correct explanation of Statement-I.

C

Statement-I is true, Statement-II is false.

D

Statement-I is false, Statement -II is true.
