For the given general term an, write an expression using $\Sigma$ to represent the indicated p to represent the indicated partial sum.
-$a _ { n } = \frac { n } { n - 9 },$ third partial sum
A) $\sum _ { i = 1 } ^ { 3 } \frac { i } { i - 9 }$
B) $\sum _ { i = 1 } ^ { n } \frac { i } { i - 9 }$
C) $\sum _ { i = 0 } ^ { 3 } \frac { i } { i - 9 }$
D) $\sum _ { i = 0 } ^ { 2 } \frac { i } { i - 9 }$

The third partial sum involves summing the first three terms of the sequence, which corresponds to substituting $i = 1, 2, 3$ into the given general term $a_n = \frac{n}{n-9}$. Therefore, the correct expression is $\sum _ { i = 1 } ^ { 3 } \frac { i } { i - 9 }$.
