1. Not sufficient
as we dont know anything about L
2. Not sufficient
we can consider a line passing through 3,3 and 0,0 => line passes through origin
we can consider another line passing through 3,3 and not passing through 0,0 (lets say 5,0) => line does not pass through origin
together , 3,3 is not on the circle. we can still consider the same examples as in 2 . Hence not sufficient.
Answer is E.

Please advise.

+1 for option E. Both statements together are not sufficient. The line passes through (3,3) and may or may not intersect the circle centered at origin and with a radius of 3.
