The following code is intended to print all EV career roles from a list, but it causes an error:

ev_roles = ["Engineer", "Sales", "Technician"]
for i in range(len(ev_roles)+1):
    print(ev_roles[i])

What is the error and how to fix it?

AIndexError; change range to len(ev_roles)

BSyntaxError; add colon after for loop

CTypeError; convert list to string

DNo error; code runs fine

Step-by-Step Solution

Solution:

Step 1: Identify cause of error
range(len(ev_roles)+1) goes from 0 to 3, but ev_roles has indices 0 to 2, so index 3 is out of range causing IndexError.
Step 2: Fix the range to avoid out-of-bounds
Change range to len(ev_roles) so loop runs 0 to 2, matching list indices.
Final Answer:
IndexError; change range to len(ev_roles) -> Option A
Quick Check:
Loop index must match list length [OK]

Quick Trick: Loop up to len(list), not len(list)+1 [OK]
