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.
