PRT is a tangent to a circle with centre O, at the point R on it. Diameter SQ of the circle is produced to meet the tangent at P and QR is joined. If `angle QRP =28^@`, then the measure of `angle SPR` is: /
PRT एक वृत्त, जिसका केंद्र O है, पर स्थित बिंदु R से जाने वाली स्पर्श रेखा है | वत्त के व्यास SQ को बढ़ाया जाता है जो स्पर्श रेखा से P पर मिलता है तथा QR को मिलाया जाता है | यदि `angle QRP = 28^@` है तो `angle SPR` का मान क्या होगा ?

A

`29^@`

B

`34^@`

C

`62^@`

D

`32^@`
