Solution

The correct option is D Assertion is false but Reason is true
Assertion given is The spheres $x^{2} + y^{2} + z^{2} = 64$
$x^{2} + y^{2} + z^{2} - 12 x + 4 y - 6 z + 48 = 0$ touch externally
hence Assertion is false
Reason given is the distance between the centres of spheres is equal to the sum of their radii.
hence Assertion is false but Reason is true.
