Respuesta :

Answer:

The answer is "other_var".

Explanation:

In java programming language the variable name must be Case-sensitive, and it uses unlimited pattern, beginning from a letter, of Unicode letters and digits, the "$" sign and the underscore " _", and the incorrect choice can be defined as follows:

  • In choice "make.use", it is wrong because it does not use "."
  • In choice "else", it is wrong because it is a keyword.
  • In choice "alt name ", it is wrong because it uses the space, which is not allowed.
