def calculate(x)
  return x * 2 if x > 5
  x + 10
end

Bnil

C13

D10

Step-by-Step Solution

Solution:

Step 1: Evaluate the condition in the return statement
The return x * 2 happens only if x > 5. Here, x is 3, so condition is false.
Step 2: Determine the returned value without explicit return
Since the condition is false, the method returns the last expression x + 10, which is 3 + 10 = 13.
Final Answer:
13 -> Option C
Quick Check:
Return with condition skips if false; last expression returned [OK]

Quick Trick: Return with condition only triggers if true; else last line returns [OK]
