Answer #1

Execution of the program starts from the main function

Initially

item = "birthday card"

price = 10

howmany = 40

At line 24, we encounter a function call. Now, control moves to getAmount() function

Now, we have the following values

priceP = 10

itemP = "birthday card"

howmanyP = 40

totalP = 10 as totalP = priceP

Since itemP = "birthday card" and howmanyP = 40, we execute from line 10

priceP = priceP + 10/5

= 10 + 2

= 12

New value of priceP = 12

total+ = priceP which means total = total + priceP

New value of total = 22

Since priceP is equal less to 12, we will update itemP = "pencil"

howmanyP = 50

The return statement will send total to main function

After the execution of line 14, we have the following values

priceP = 12

total = 22

howmanyP = 50

itemP = "pencil"

Note: The value of the fee variable is wrong in all the options. It must be 22 as the value of total is returned

Options 2 and 3 are incorrect as itemP value is "pencil"

In Options 1 and 4, the values of other variables are correct except for the fee's value. Since the variable fee's value isn't correct, it is hard to predict which option is correct.

But options 2 and 3 are certianly incorrect.
