Question
Assertion(A): Let 
and 
be three points such that 
and 
then OABC is a tetrahedron.
Reason(R): Let and be three points such that 
are non-coplanar, then OABC is a tetrahedron, where O is the origin.
- If both (A) and (R) are true, and (R) is the correct explanation of (A).
- If both (A) and (R) are true but (R) is not the correct explanation of (A).
- If (A) is true but (R) is false.
- If (A) is false but (R) is true.
The correct answer is: If (A) is false but (R) is true.
Since 
= 0
