Answer:
The correct version of a mixed cell reference is $C14.
Step-by-step explanation:
A mixed cell reference refers to a cell reference in a formula that contains a mix of relative and absolute references. In a mixed reference, either the row or column reference is absolute, while the other is relative. The dollar sign ($) is used to denote the absolute reference.
In the given options, only $C14 contains a mixed reference. The dollar sign ($) is used to make column reference (C) absolute while the row reference (14) remains relative. Therefore, $C14 is the correct version of a mixed cell reference.
The other options are either fully absolute or fully relative cell references, but not mixed cell references. $F$1 is an example of a fully absolute reference, P1 is an example of a fully relative reference, and $K12$ is an example of a fully absolute reference with both row and column references absolute.
