If the coefficients of $$r$$th, $$(r + 1)$$th and $$(r + 2)$$th terms in the binomial expansion of $$(1 + y)^m$$ are in A.P., then $$m$$ and $$r$$ satisfy the equation

A

$$m^2 - m(4r - 1) + 4r^2 - 2 = 0$$

B

$$m^2 - m(4r + 1) + 4r^2 + 2 = 0$$

C

$$m^2 - m(4r + 1) + 4r^2 - 2 = 0$$

D

$$m^2 - m(4r - 1) + 4r^2 + 2 = 0$$
