Explanation

Choice A is correct. It’s given that a special camera is used for underwater ocean research, and this camera is at a depth of $39$ fathoms. It's also given that $1$ fathom is equal to $6$ feet. Thus, $39$ fathoms is equivalent to $left parenthesis 39 fathoms right parenthesis left parenthesis StartFraction 6 feet Over 1 fathom EndFraction right parenthesis$ , or $234$ feet. Therefore, the camera's depth, in feet, is $234$ .

Choice B is incorrect. This is the camera's depth, in feet, if the camera is at a depth of $19.5$ fathoms.

Choice C is incorrect. This is the camera's depth, in feet, if the camera is at a depth of $7.5$ fathoms.

Choice D is incorrect and may result from conceptual or calculation errors.
