Given two three bit numbers $a_{2}a_{1}a_{0}$ and $b_{2}b_{1}b_{0}$ and $c$ the carry in, the function that represents the carry generate function when these two numbers are added is:

(A)

$a_{2}b_{2}+a_{2}a_{1}b_{1}+a_{2}a_{1}a_{0}b_{0}+a_{2}a_{0}b_{1}b_{0}+a_{1}b_{2}b_{1}+a_{1}a_{0}b_{2}b_{0}+a_{0}b_{2}b_{1}b_{0}$

(B)

$a_{2}b_{2}+a_{2}b_{1}b_{0}+a_{2}a_{1}b_{1}b_{0}+a_{1}a_{0}b_{2}b_{1}+a_{1}a_{0}b_{2}+a_{1}a_{0}b_{2}b_{0}+a_{2}a_{0}b_{1}b_{0}$

(C)

$a_{2}+b_{2}+(a_{2}\oplus b_{2}) ( a_{1}+b_{1}+(a_{1}\oplus b_{1})+(a_{0}+b_{0}))$

(D)

$a_{2}b_{2}+\overline{a_{2}}a_{1}b_{1}+\overline{a_{2}a_{1}}a_{0}b_{0}+\overline{a_{2}}a_{0}\overline{b_{1}}b_{0}+a_{1}\overline{b_{2}}b_{1}+\overline{a_{1}}a_{0}\overline{b_{2}}b_{0}+a_{0}\overline{b_{2}b_{1}}b_{0}$
