Step-by-Step Solution

Solution:

Step 1: Recall main function signature options
Kotlin's main can accept parameters like args: Array<String> for command-line arguments.
Step 2: Evaluate each statement
The statement 'It can have parameters to accept command-line arguments.' is true. 'It must always have a return type of Int.' is false because main returns Unit by default. 'It cannot be declared more than once in a program.' is false as multiple mains can exist in different files. 'It is optional and the program runs without it.' is false because main is required.
Final Answer:
It can have parameters to accept command-line arguments. -> Option B
Quick Check:
Main parameters = Command-line args allowed [OK]

Quick Trick: Main can take args to receive command-line inputs [OK]
