NULL is a symbol or concept which is used where no value is defined. So the NULL can be defined there where no value exists. The above question asked about the NULL that what is it. So--

• The option A states that the NULL is the same as 0 but the NULL is defined when there is no value.
• The option B states that the NULL is the same as blank but the (" ") also states the blank character but the NULL is defined when there is no value.
• Option C states that the NULL can be 0 or blank but NULL is not both of them because it is described above.
