(a) 2 and 6 only
(b) 2, 4, and 6 only

(d) 1, 2, 3, 4, and 6 only
(e) 1, 2, 3, 4, 5, and 6

Answer: E

The important takeaway here is that "intersect" does not necessarily mean "pass through"
So, a line that is tangent to a circle (touching the circle but not passing through it) can be said to intersect the circle. To intersect is to share a common point.

Cheers,
