Option a would be the correct one.

Explanation:

The above equation is terms of t. The first thing we got to do is to remove this parameter. We know that sec2x=1+tanx So the above equation can be written as y=1+x2 or y1=x2.

Comparing it with the standard equation of parabola x2=4ay .This represents a parabola with axis as the axis of symmetry and which is concave up.
Hence option a is correct.

Hope it helps!!
