Detailed Solution

Concept: Since a number that is divisible by two serves as the definition of an even number, an even number should generally be divisible by two. This indicates that any integer, such as "n," and 2 are both factors in the general form of an even number. As a result, we shall have the common form of an even integer.
Knowing that an even number is one that can be divided by two, we must discover the even number's general form, which must also be a number that can be divided by two. The general form contains 2 because a number must have 2 as one of its factors in order to be divisible by 2, and since it is a general form, let's multiply 2 by "n," where "n" can be any integer.
We can conclude from the discussion we just had above that an even integer generally takes the form 2n.
Hence, the correct answer is option 2.
