Q.	If the distance from a fixed straight line is equal to the distance from a fixed point then what is the name of the conic section?
A.	ellipse
B.	parabola
C.	hyperbola
D.	circle
Answer» B. parabola
Explanation: the fixed straight line is called as directrix and the fixed point is called as a focus. eccentricity is defined as the ratio of the distance from the focus to the distance from the directrix and it is denoted by e.
