Answer:
b. the do loop will always execute the body of the loop at least once
Explanation:
The do loop will always execute the body of the loop at least once becuase it is an exit loop, that means the condition is always checked at the end, where as while loop execute hte body of the loop zero times as it is an entry loop and the condition will be checked prior to the execution of body of the loop.
do loop structure is as shown below
do{
}while()
So it executes the block atleast once and then checks the condition
Hence, the do loop will always execute the body of the loop at least once.
