• B)Symmetric with respect to polar axis \(| r | = 9\) when \(\theta = \pi\) \[r = 0 \text { when } \theta = \frac { \pi } { 3 } , \frac { 5 \pi } { 3 }\]
• C)Symmetric with respect to polar axis \(| r | = 9\) when \(\theta = \pi\) \[r = 0 \text { when } \theta = \frac { \pi } { 3 } , \frac { 5 \pi } { 3 }\]
• D)Symmetric with respect to polar axis \(| r | = 9\) when \(\theta = \pi\) \[r = 0 \text { when } \theta = \frac { \pi } { 3 } , \frac { 5 \pi } { 3 }\]
• E)Symmetric with respect to polar axis \(| r | = 9\) when \(\theta = \pi\) \[r = 0 \text { when } \theta = \frac { \pi } { 3 } , \frac { 5 \pi } { 3 }\]
