Answer:
b. 2.9!
Explanation:
There are is a mistake in the question.
Suppose the group consist of 10 kids and 2 adults, the number of ways in which they can form the line is:
= 2! 10!
= 2× 1× 10!
= 2.10!
But since that is not in the given option.
Let assume that the group consists of 9 kids and 2 adults, the number of ways in which they can form the line is:
No of ways the kids can be permutated = 9 ways
No of ways the adult can be permutated = two ways.
Thus; the number of ways in which they can form the line = 2! 9!
= 2 × 1× 9!
= 2.9!

A constructor exists just a special type of subroutine that instantiates an object from the class.
<h3>What is constructor?</h3>
A constructor exists as a special kind of subroutine in a class. It maintains the same name as the name of the class, and it has no return type, not even void. A constructor exists called with the new operator in order to create a new object.
A constructor exists as a special process of a class or structure in object-oriented programming that initializes a newly constructed object of that type. Whenever an object exists created, the constructor is called automatically. A constructor in Java exists as a special method that is utilized to initialize objects. The constructor exists called when an object of a class is created.
A subroutine exists as a sequence of program instructions that serves a specific task, packaged as a unit. This unit can then be utilized in programs wherever that separate task should be performed.
Hence, A constructor exists just a special type of subroutine that instantiates an object from the class.
