Ruby - Error Handling

Identify the error in this Ruby code snippet:

def divide(a, b)
  raise "Cannot divide by zero" if b = 0
  a / b
end

puts divide(10, 0)

ADivision operator is incorrect

BMissing parentheses in raise statement

CUsing assignment (=) instead of comparison (==) in the if condition

DMethod divide is not defined

Step-by-Step Solution

Solution:

Step 1: Check the if condition syntax
The condition uses b = 0 which assigns 0 to b instead of comparing it. This is a common mistake.
Step 2: Understand the impact
Because of assignment, b becomes 0, and since 0 is falsy in Ruby, the condition evaluates to false, so the raise is not triggered. The intended check is b == 0.
Final Answer:
Using assignment (=) instead of comparison (==) in the if condition -> Option C
Quick Check:
Use == for comparison, not = [OK]

Quick Trick: Use == to compare, not = which assigns [OK]
