Which of these is a valid use of the ternary operator in Ruby?

Aresult = score > 50 ? 'Pass' : 'Fail'

Bif score > 50 then 'Pass' else 'Fail' end

Cscore > 50 ? 'Pass' and 'Fail'

Dresult = score > 50 : 'Pass' ? 'Fail'

Step-by-Step Solution

Solution:

Step 1: Check the syntax of each option
result = score > 50 ? 'Pass' : 'Fail' uses the correct ternary format: condition ? true_value : false_value. if score > 50 then 'Pass' else 'Fail' end is an if-else statement, not ternary. score > 50 ? 'Pass' and 'Fail' uses 'and' incorrectly. result = score > 50 : 'Pass' ? 'Fail' mixes symbols wrongly.
Step 2: Confirm the correct ternary syntax
Only result = score > 50 ? 'Pass' : 'Fail' correctly assigns 'Pass' or 'Fail' based on the condition using the ternary operator.
Final Answer:
result = score > 50 ? 'Pass' : 'Fail' -> Option A
Quick Check:
Valid ternary syntax = result = score > 50 ? 'Pass' : 'Fail' [OK]
