The println statement uses $PI which means it will replace $PI with the value of the constant PI.
Step 2: Check the constant value and output
PI is declared as 3.14, so the output will be "Value of PI: 3.14" exactly.
Final Answer:
Value of PI: 3.14 -> Option C
Quick Check:
String interpolation replaces $PI with 3.14 [OK]

Quick Trick: Look for $variable inside strings for value substitution [OK]
