their spies kept them informed by sending secret messages.

Explanation:

The Battle of Britain relied heavily on air combat, and Britain's early and effective use of radar was a decisive factor. Radar allowed the Royal Air Force to detect incoming German aircraft early, conserve resources, and mount targeted defenses. While leadership and determination played roles, radar was a key material advantage. The German Luftwaffe was not outmatched in raw power, and espionage was not the primary reason for British success.

Answer:

A. Their radar equipment was effective.
