A fish is 50.0 cm below the surface of a pond (index of refraction for water is 1.33). For a viewer directly above the fish, the fish appears to be placed
A) 37.6 cm below the surface of the pond.
B) 50.0 cm below the surface of the pond.
C) 66.5 cm below the surface of the pond.
D) None of the above is correct.

The apparent depth of the fish is calculated using the formula: $d' = \frac{d}{n}$, where $d'$ is the apparent depth, $d$ is the real depth (50.0 cm), and $n$ is the refractive index of water (1.33). Plugging in the values, we get $d' = \frac{50.0 \, \text{cm}}{1.33} \approx 37.6 \, \text{cm}$.
