A$)$ Explain about Forward Chaining in propositional logic.

B$)$ Consider a complex system with multiple sensors and actuators. Using forward chaining, determine the sequence of actions required to achieve a specific goal while satisfying various constraints and conditions.

C$)$ Given a set of propositional clauses representing a logical puzzle or game, use forward chaining to find a solution or make a series of moves to reach a winning state.

D$)$ Create a knowledge base in propositional logic for an autonomous driving system. Use forward chaining to determine the optimal actions for the vehicle to navigate through traffic and reach its destination safely.

E$)$ Imagine a scenario where you have a propositional logic knowledge base representing the behaviour of a robot in a dynamic environment. Use forward chaining to plan a path for the robot to collect objects while avoiding obstacles and hazards.
