Let L and L2 denote the lines r=+^(-+2+2k),^ R and r= (2 -+2k), = R respectively. If L3 is a line which is perpendicular to both L and L and cuts both of them, then which of the following options describe (s) L3? A. =(4+j+k)+1(2+2-k), ter +t T=(2i-j+2k)+1(2+2j-k).teR B. r= r= (2+k)+1(2+2_k),t R D. F=t(21+2j-k),teR
