Answer: b. 37, 40, 41, 42
Explanation:
The next four octal numbers after 36 is 37, 40, 41, 42.
The octal numeral system, which is also referred to as "oct" for short, is simply base-8 number system.
It is a number system whereby only digits from 0 to 7 are used and there are no letters or numbers that are above 8 that are used.
In this case, after 36, the next number will be 37 after which we go to 40 as we can't write 38 in the octal system. Therefore, the next four octal numbers after 36 is 37, 40, 41, 42.
