The correct choice is (a) lower_case_table_names

Easy explanation: In MySQL, by default the alias names are case sensitive. An alias can hence be specified in any letter case, upper, lower or mixed. If the variable ‘lower_case_table_names’ is non zero, the alias names of tables are not case sensitive.
