Ruby - Error Handling

Aattempts = 0 begin # risky code attempts += 1 rescue retry if attempts < 3 end

Battempts = 0 begin attempts += 1 # risky code rescue retry end

Cattempts = 0 begin # risky code rescue retry unless attempts > 3 end

Dattempts = 0 begin # risky code rescue attempts += 1 retry if attempts < 3 end

Step-by-Step Solution

Solution:

Step 1: Understand retry with counter
We must increment attempts inside rescue to count retries after errors.
Step 2: Check retry condition
Retry only if attempts < 3 to limit retries to 3 times.
Step 3: Verify code correctness
attempts = 0 begin # risky code rescue attempts += 1 retry if attempts < 3 end increments attempts in rescue and retries if attempts < 3, correctly limiting retries.
Final Answer:
attempts = 0 begin # risky code rescue attempts += 1 retry if attempts < 3 end -> Option D
Quick Check:
Increment attempts in rescue before retry = C [OK]

Quick Trick: Increment attempts in rescue before retry condition [OK]
