If the coefficients of
\(r^{\text{th}\text{~}},(r + 1)^{\text{th}\text{~}}\) and
\((r + 2)^{\text{th}\text{~}}\) 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
\(m^{2} - m(4r - 1) + 4r^{2} - 2 = 0\)\\
