Value returned by $\text{fun}(95) = \text{fun}(\text{fun}(106))$
$\qquad\qquad= \text{fun}(96)$
$\qquad\qquad= \text{fun}(\text{fun}(107))$
$\qquad\qquad= \text{fun}(97)$
$\qquad\qquad= \text{fun}(\text{fun}(108))$
$\qquad\qquad= \text{fun}(98)$
$\qquad\qquad = \text{fun}(\text{fun}(109))$
$\qquad\qquad= \text{fun}(99)$
$\qquad\qquad= \text{fun}(\text{fun}(110))$
$\qquad\qquad= \text{fun}(100) $
$\qquad\qquad= \text{fun}(\text{fun}(111)) $
$\qquad\qquad= \text{fun}(101) = 91.$
Correct Answer: $C$
