Match the options of List 1 with the options of List 2 f or the circle $\mathrm{x}^{2}+\mathrm{y}^{2}=49$ List I List II

Using the tangent length formula d squared minus r squared for point (6,4) and circle radius 7, the length is the square root of 52 squared minus 7 squared, which is the square root of 3, matching A to 4. The chord of contact length formula gives 7 times the square root of 3 squared divided by 52, matching B to 1. The distance from (6,4) to the origin is the square root of 6 squared plus 4 squared, matching C to 2. The shortest distance to the circle is the square root of 52 minus 7, matching D to 3.
