Matter composed of the antiparticles of corresponding particles in ordinary matter (correct)

What is the main reason for the lack of macroscopic amount of antimatter assembly?

Lack of interest in antimatter research
Extreme cost and difficulty of production and handling (correct)
Inability to generate sufficient antiparticles
Regulatory restrictions on antimatter experiments

What happens when a particle and its antiparticle partner collide?
