Which type of rocket warhead produces blast, fragmentation, and mining effects?

The correct answer is high explosive. High explosive warheads are specifically designed to create a powerful blast effect upon detonation. This type of warhead generates a significant shock wave that can cause extensive damage to structures and personnel. Additionally, high explosive warheads produce shrapnel upon detonation, leading to fragmentation effects that can injure or kill nearby targets through the dispersal of metal fragments.

High explosive warheads can also have mining effects, as they can penetrate into the ground or materials upon impact, leading to secondary effects that can disrupt nearby targets and create secondary explosions. The multifunctionality of high explosive warheads makes them versatile in various combat situations, providing both destructive blast and lethal fragmentation.

The other options are distinct in their design and effects: incendiary warheads primarily focus on causing fire damage, while white phosphorus is used for marking or obscuring visibility rather than causing significant fragmentation damage. Thermobaric warheads create a sustained blast wave and can be effective against enclosed spaces, but they do not emphasize fragmentation effects to the same extent as high explosives. Therefore, high explosive is the most appropriate choice for producing blast, fragmentation, and mining effects.
