Answer:

(d) ∠AIS

Explanation:

The tangent SF intersects the circle at one point, point I. Any angle it forms with a chord must be a chord that terminates at point I. There are two of them: AI and CI.

The angles these chords make with tangent SF are ...

• ∠AIS
• ∠AIF
• ∠CIS
• ∠CIF

Of these, only the first (∠AIS) is listed among the answer choices.
