Carefully study the following Python program that uses functions from the random module to generate values and display selected elements from a Python list. Read the code and answer the questions that follow:
_______________ # Line 1
C = list('VIBGYOR')
Extra = 1 + int(2 * random())
Low = randrange(2, 6, 2)
High = randint(Low, 6)
for i in range(Low, High + Extra):
print(C[i], end='#')Questions:
(A) Suggest an appropriate import statement for Line 1 in the above code so that all functions of the random module can be used directly in the program without using the module name prefix.
(B) Identify all possible values that the variable Low can take during program execution.
(C) Based on the logic of the code, determine which one of the given options cannot be a valid output of the program. Briefly justify your answer.
Options:
1. B#G#Y# 2. B#G#Y#O# 3. I#B#G#Y# 4. Y#O#
(D) Identify the situation in which the program may generate a runtime exception. Specify the combination of values of Low, High and Extra that may cause the exception, and name the type of exception raised.

Show answer & explanation
(A) Import Statement:from random import *
Reason: It allows direct use of functions like randrange(), randint() and random() without module prefix.
(B) Possible values of Low:2, 4
Reason: randrange(2, 6, 2) generates values starting from 2 up to (but not including) 6 with step 2.
(C) Invalid Output: I#B#G#Y#
Reason: Loop always starts from index 2 or 4, so index 1 ('I') cannot occur.
(D) Runtime Exception:
Condition: When High + Extra ≥ 7 (list index exceeds valid range 0–6).
Example: Low = 4, High = 6, Extra = 2 → loop runs till index 7.
Exception: IndexError: list index out of range
