A) \[-3\sqrt{2}\]
B) \[3\sqrt{2}\]
C) \[-3/\sqrt{2}\]
D) \[3/\sqrt{2}\]
Correct Answer: B
Solution :
Distance between focus and directrix is \[=\left| \frac{3-4-2}{\sqrt{2}} \right|=\frac{\pm 3}{\sqrt{2}}\] Hence latus rectum \[=3\sqrt{2}\] (Since latus rectum is two times the distance between focus and directrix).
