Answer:

Option (2)

Explanation:

From the picture attached,

Length of OG = 16

Length of PE = 9

Let us draw a perpendicular AE to OG which intersects at A.

Length of AG = OG - PE

= 16 - 9

= 7

Length of AE = OP

= OT + TP

= OG + PE [Since, OT = OG and TP = PE, radii of the circles]

= 16 + 9

= 25

By applying Pythagoras theorem in ΔGAE,

GE² = AG² + AE²

GE² = 7² + 25²

GE = √674

GE = 25.96

≈ 26

Option (2) will be the correct option.
