Ruby - Error Handling

Consider this Ruby code:

def safe_divide(a, b)
  begin
    result = a / b
  rescue ZeroDivisionError
    result = nil
  end
  result
end

puts safe_divide(10, 0)
puts safe_divide(10, 2)

What is the output?

A10 5

Bnil 5

CError 5

D0 5

Step-by-Step Solution

Solution:

Step 1: Analyze safe_divide with zero divisor
Dividing by zero raises ZeroDivisionError, caught by rescue, sets result to nil.
Step 2: Analyze safe_divide with divisor 2
Division succeeds, result is 5.
Final Answer:
nil 5 -> Option B
Quick Check:
Rescue returns nil on error = D [OK]

Quick Trick: Rescue can assign fallback values on error [OK]

Common Mistakes:

Expecting error instead of nil
Confusing zero with nil
Ignoring rescue effect
