Answer 1

Answer:

1. if

2.immature

3.block after if

4. teenager

Explanation:

1. if is a conditional statement depending upon the condition the control is given to the system
ex -
if(condition) {    
statement 1; //executes when condition is true  
}    

whereas for and while are the loop statements which is executed on the control of the system
ex -
while(condition){    
//looping statements    
}    

for(initialize; condition ; incriment / decrement) {  
//looping statements      
}

2. As the value of age inputed by the user is 21 which turns if statement as false hence the statement under if is not executed hence else part statement is executed.

3.If the condition mentioned in the 'if' block is False then block after if is considered and is executed

4. Here the value of age entered by the user is 13 so the statement under if is not executed as the condition is not satisfied whereas statement under elif is executed as the condition under elif command is satisfied hence the output we got is teenager.
