If $AB$ is a diameter of a circle and $C$ is any point on the circle (other than $A,B$ ), then $\angle ACB$ equals—

a $30^{\circ}$
b $45^{\circ}$
c $60^{\circ}$
d $90^{\circ}$

ব্যাখ্যা

With $AB$ a diameter, the angle $\angle ACB$ is inscribed in a semicircle and equals half the straight central angle $\angle AOB=180^\circ$ . Therefore $\angle ACB=90^\circ$ for every position of $C$ .
