Use Properties of Logarithms to Condense the Logarithmic Expression $$\frac { 1 } { 3 } ( \log 9 x + \log 9 y ) - 4 \log 9 ( x + 3 )$$

Use properties of logarithms to condense the logarithmic expression. Write the expression as a single logarithm whose coefficient is 1. Where possible, evaluate logarithmic expressions.
- $$\frac { 1 } { 3 } ( \log 9 x + \log 9 y ) - 4 \log 9 ( x + 3 )$$

A) $\log _ { 9 } \frac { \sqrt [ 3 ] { x y } } { 4 ( x + 3 ) }$
B) $\log 9 \frac { \sqrt [ 3 ] { x } + \sqrt [ 3 ] { y } } { ( x + 3 ) ^ { 4 } }$
C) $\log _ { 9 } \frac { \sqrt [ 3 ] { x + y } } { ( x + 3 ) ^ { 4 } }$
D) $\log _ { 9 } \frac { \sqrt [ 3 ] { x y } } { ( x + 3 ) ^ { 4 } }$
