What is the maximum length for alias names in terms of characters?(a) 64(b) 128(c) 256(d) 32

Answer» The correct answer is (c) 256

To explain I would say: The identifiers in MySQL have a maximum length of 64 characters. However, the alias names for identifiers can have the number of characters up to 256. Aliases can also be quoted or unquoted.
