Answer is Right!
The missing number is 3.
The numbers in the sequence are increasing by 2, starting with 1. Therefore, the next number in the sequence is 1 + 2 = 3.
Option A is incorrect because 9 is not in the sequence.
Option B is incorrect because 0 is not in the sequence.
Option C is incorrect because 1 is already in the sequence.
Option D is correct because 3 is the next number in the sequence.
