- $$x ^ { 2 } + 4 y ^ { 2 } = 4$$

• A) \(r ^ { 2 } \left( \cos ^ { 2 } \theta + 4 \sin ^ { 2 } \theta \right) = 4\)
• B) \(\cos ^ { 2 } \theta + 4 \sin ^ { 2 } \theta = 4 r\)
• C) \(4 \cos ^ { 2 } \theta + \sin ^ { 2 } \theta = 4 \mathrm { r }\)
• D) \(r ^ { 2 } \left( 4 \cos ^ { 2 } \theta + \sin ^ { 2 } \theta \right) = 4\)
