Which flare type burns 25-50 seconds and emits green, red, and white?

• A. Star Cluster
• B. Star Parachute
• C. Smoke parachute
• D. Flares

Answer: (B)

The key idea is a signaling flare that stays aloft and provides a multi-color display. A star parachute flare is designed to burn for a relatively long duration, typically about 25–50 seconds, while drifting downward under a parachute. As it burns, it releases colored stars that produce green, red, and white light, making the signal easily visible over distance and at night. The parachute helps slow descent and keeps the flare visible for observers on the ground.

Other flare types behave differently: a star cluster flare bursts into many colored stars all at once but doesn’t usually sustain a long, controlled burn like 25–50 seconds. A smoke parachute emits colored smoke rather than colored flame, so it won’t produce the green/red/white flame signature. General flares can produce a single color or a shorter burn, but they aren’t the combination of long duration and multi-color light that the star parachute provides.
