Q1 Which of the following statements is true if x (a character array) is added (+) to a y (2 x 2 double)? Select one: a. Variable x will be converted into a double and then concatenated with y to create new ASCII-type variable b. The addition operation (+) cannot be performed c. Variable y will be converted into a string and then concatenated with x to create a new string-type variable d. ASCII values of x are added to y to create a new double-type variable e. It is equivalent to the statement x == y and creates a logical-type variable
