The compiler determines the data type for the variable based on the value assigned to it. In this case, the value is a decimal number (14.95), which requires a data type that supports decimal points. The options provided are int (integer), bool (boolean), char (character), string (string of characters), and double (decimal number). Only double supports decimal numbers, so it is the best choice for the variable "cost".
