The correct option is B pattern
A repeated arrangement of numbers or shapes which follows a rule is called a pattern.
For example, 1,3,5,6,7,...
Here, after 1, the next number is 3, i.e., we are adding 2 with 1.
After 3, the next number is 5, i.e., we are adding 2 with 3.
So, the change is going in the same way, that is, we are adding 2 to the current number.
So, there is a repeated arrangement of numbers that follows a rule of adding 2 to every number to get the next number. For example, after 1, it would be 3; after 3, it would be 5 ; after 5, it would be 7, and so on.
This is called a pattern.
