Which of the following gives the value of magnetic field according to, Biot-Savart’s law

Using Biot-Savart’s law, derive an expression for magnetic field at any point on axial line of a current carrying circular loop. Hence, find magnitude of magnetic field intensity at the centre of circular coil.
