To evaluate the double integral $$\int\limits_0^8 {\left( {\int\limits_{y/2}^{\left( {y/2} \right) + 1} {\left( {{{2x - y} \over 2}} \right)dx} } \right)dy,\,\,} $$ we make the substitution $$u = \left( {{{2x - y} \over 2}} \right)$$ and $$v = {y \over 2}.$$ The integral will reduce to
A
$$\int\limits_0^4 {\left( {\int\limits_0^2 {2udu} } \right)dv} $$
B
$$\int\limits_0^4 {\left( {\int\limits_0^1 {2udu} } \right)dv} $$
C
$$\int\limits_0^4 {\left( {\int\limits_0^1 {udu} } \right)dv} $$
D
$$\int\limits_0^4 {\left( {\int\limits_0^{21} {2udu} } \right)dv} $$
