Which risk increases when the temperature of a solid rocket propellant decreases significantly?

A)Reduced burn rate instability
B)Increased propellant regression rate
C)Elevated catalytic cracking sensitivity
D)Accelerated deflagration-to-detonation transition

💡 Explanation

Decreasing the propellant temperature raises the risk of DDT because the **Arrhenius equation**. Low temperatures depress initial burn rates; therefore, a deflagration can transition to a detonation far more easily, rather than burning cleanly due to pressure increases.
