Q.	If the distance from the focus is 3 units and the distance from the directrix is 3 units, then what is the name of the conic section?
A.	ellipse
B.	hyperbola
C.	circle
D.	parabola
Answer» D. parabola
Explanation: eccentricity is defined as the ratio of the distance from the focus to the distance from the directrix and it is denoted by e. therefore, by definition, e = 3 ÷ 3 = 1. hence the conic section is called as a parabola.
