Answer: The correct answer is alpha radiation.

Step-by-step explanation:

For the given options:

Option 1: Alpha

Alpha decay is defined as the process in which alpha particle is emitted. In this process, a heavier nuclei decays into a lighter nuclei. The alpha particle released carries a charge of +2 units. The released alpha particle is also known as helium nucleus.


_Z^A\textrm{X}\rightarrow _(Z-2)^(A-4)\textrm{Y}+_2^4\alpha

Option 2: Beta

Beta decay is defined as the process in which beta particle is emitted. In this process, a neutron gets converted to a proton and an electron. The released beta particle is also known as electron.


_Z^A\textrm{X}\rightarrow _(Z+1)^A\textrm{Y}+_(-1)^0\beta

Option 3: Gamma

Gamma decay is defined as the process in which an unstable nuclei gives off excess energy by a spontaneous electromagnetic process and thus releases
\gamma -radiations. These radiations does not carry any charge and are electrically neutral.


_Z^A\textrm{X}^*\rightarrow _Z^A\textrm{X}+_0^0\gamma

Option 4: Isotope

Isotope is defined as the chemical specie which belong to the same element but differ in their molecular mass.

Hence, the correct answer is alpha radiation.
