Explanation:

In an algebraic expression, a variable is a symbol that represents an unknown quantity and can take on different values. In the expression \(-y^2 - 2y - 4\), \(y\) is the symbol that represents the variable (it can be replaced by different numbers), while \(-4\), \(-2\), and \(-1\) (or the coefficients and constants) are fixed values in this context.

Answer:

A. \( y \)
