B. 25
C. 30
D. 35

Answer:
The output is 35
Explanation:
Required
Determine the output on line 5
We start by analysing the program line by line.
On line 1: kit = 20
On line 2: roo = 10
On line 3: kit = kit + 5
Substitute 20 for kit.
So, we have
kit = 20 + 5
kit = 25
On line 4:
roo = kit + roo
Substitute values for kit and too
roo = 25 + 10
roo = 35
On line 5: Output roo
So, 35 is displayed as an output
