To determine which of the given REXX expressions will generate an error, let's go through each option:

A. 10 / number1 - This expression will generate an error because number1 has not been assigned a value. It is attempting to perform division with an undefined variable.

B. name || 'number2' - This expression will concatenate the value of the variable name with the string 'number2'. It will not generate an error.

C. number2 * 3 - This expression will multiply the value of the variable number2 by 3. It will not generate an error.

D. name > number2 - This expression will compare the value of the variable name with the value of the variable number2. It will not generate an error.

Therefore, the correct answer is A. This expression will generate an error because number1 has not been assigned a value.
