Bpublic class Car extends Engine, Wheels {}

Cpublic class Car implements Engine, Wheels {}

Dpublic class Car extends Engine implements Wheels {}

Step-by-Step Solution

Solution:

Step 1: Recall Java syntax for implementing multiple interfaces
Java uses the keyword implements followed by a comma-separated list of interfaces.
Step 2: Check each option's syntax
public class Car implements Engine, Wheels {} correctly uses implements Engine, Wheels. Options B and D incorrectly use extends for interfaces or mix keywords wrongly. public class Car implements Engine & Wheels {} uses an invalid '&' symbol.
Final Answer:
public class Car implements Engine, Wheels {} -> Option C

Multiple interfaces use comma with implements = A [OK]
