Complete the Number: Make 62_ Even by Divisibility

To solve this problem, we identify the numbers that can make $62\text{ }_{—}$ divisible by 2:

• A number is divisible by 2 if its last digit is even.
• In our choices, the even numbers are $0$, as it satisfies the divisibility rule for 2.

Substitute the even number:

• Try $0$: The number becomes $620$.
• $620 \div 2 = 310$, which is an integer showing $620$ is divisible by 2.

Therefore, the correct digit to ensure $62\text{ }_{—}$ is divisible by 2 is 0.
