Binterface Vehicle { void Move(); }

Cclass abstract Vehicle { public void Move(); }

Step-by-Step Solution

In C#, the keyword abstract precedes class, followed by the class name and method declarations.
Step 2: Check each option
abstract class Vehicle { public abstract void Move(); } correctly uses "abstract class Vehicle" and declares an abstract method. Options A, C, and D have incorrect keyword order or use interface syntax.
Final Answer:
abstract class Vehicle { public abstract void Move(); } -> Option A

abstract class syntax = "abstract class" [OK]

Quick Trick: abstract class keyword order: 'abstract class' [OK]
