Column IColumn II
(A) If maximum and minimum distances of sphere `x^2 + y^2 + z^2- 4x+ 6y- 8z + 4= 0` from `(-0, 0,10)` are `lambda` and `mu` , then (P) `lambda + mu =6`
(B) If maximum and minimum distances of sphere `x^2 + y^2 + z^2 + 2x- 2y- 4z -19 = 0` from `(0 , 3, 4)` are `lambda` and `mu` , then (Q) `lambda + mu = 10 `
(C) If maximum and minimum distances of sphere `x^2 +y^2 +z^2 -2x-4y+2z-3=0` from `(-1,4,-2)` are `lambda` and `mu`, then (R) `lambda + mu =14`
(S) `lambda - mu =6`
(T) `lambda - mu =10`


A

`A -> (R, T); B -> (P, S); C -> (Q, S)`

B

`A -> (R, S); B -> (Q, T); C -> (P, S)`

C

`A -> (R, T); B -> (Q, S); C -> (P, S)`

D

`A -> (R, Q); B -> (T, S); C -> (P, S)`
