The lines and
Option: 1 do not intersect for any values of l and m
Option: 2 intersect for all values of l and m
Option: 3 intersect for the values when l=2 and
Option: 4 intersect for the values when l=2 and m=2
For intersection
These values of m and l do not satisfy equation (1). Hence the two lines do not intersect for any values of l and m
