Answer:
The correct answer is option (C) Alpha radiation
Explanation:
The types of radiation which are alpha, beta and gamma radiation have different penetration power.
Penetration power is the ability of each of the types of radiation to pass through matter. The more they penetrate, the more dangerous they will be.
Alpha has the least penetration power because it has large mass size
Gamma has the highest penetration power because it has no mass size
Beta has the medium penetration power because it has a small mass size
Therefore, the penetration power is affected by the size of mass they carry.
