Two \(u\) and \(v\) are parallel if and only if

Two \(u\) and \(v\) are parallel if and only if
  1. \(u\) and \(v\) have the same direction
  2. \(u\) and \(v\) have the opposite direction
  3. One of them is a scalar multiple of the other
  4. The dot product of \(u\) and \(v\) are zero

Solution

If two vectors are parallel then one is scalar multiple of others. Hence, option (c) is correct.
