- P (Posters): Posters are a visually engaging method of communication that can be used to spread awareness effectively. They are often placed in public spaces and can catch the attention of the audience.
- Q (Loudspeakers): Loudspeakers, though useful for audio communication, are not visually engaging and thus don't fit the requirement.
- R (Film shows): Film shows are highly engaging, visually captivating, and an effective method to communicate messages about population control.
- S (Street plays): Street plays are a dynamic and visual method of conveying messages. They can involve real-time performances that engage the audience and drive home the message effectively.
Given that the question asks for visually engaging methods, we can eliminate loudspeakers (Q) as they do not fit the visual requirement. Posters (P), film shows (R), and street plays (S) are all effective visual methods for educating the rural audience on population control. Hence, the correct answer is (A).
Final Answer: (A) P, R and S.
