Answer:
Option E
Explanation:
Magnetic induction at the centre of circular current carrying loop.

B1=μ0i2r (downward direction )
Magnetic induction at the centre O due to straight wire,
B2=μ02πir (upward direction)
Net magnetic induction at O,
B=B1−B2=μ0i2r−μ02π.ir
=μ0i2r[1−1π] [ downward direction]
Hence, there are no option correct.
