(A) < (B) < (D) < (C)
(B) < (C) < (D) < (A)
(B) < (A) < (D) < (C)
(B) < (C) < (A) < (D)
Explanation
In SN1 substitution reaction, reactivity of compound depends on the stability of carbocation formed in the rate determination step. Reactivity of compound will be more when it's carbocation is more stable.

So stability order of carbocation :
C > D > A > B
So stability order of carbocation :
C > D > A > B
