Problem

Let the vectors PQPQ, QRQR, RSRS, STST, TUTU and UPUP represent the sides of a regular hexagon. Statement I PQ×(RS+ST)≠0PQ \times (RS + ST) \neq 0 , because Statement II PQ×RS=0PQ \times RS = 0 and PQ×ST≠0PQ \times ST \neq 0 (1) Statement I is true, Statement II is true and Statement II is a correct explanation for Statement I. (2) Statement I is true, Statement II is true but Statement II is not a correct explanation for Statement I. (3) Statement I is true, Statement II is false. (4) Statement I is false, Statement II is true.
