Kelvin

Explanation:

Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like and  

These units of temperature are inter convertible.

As we know that there are seven fundamental SI units which are used to fine derived units . They are listed as:

1). Mass - Kilogram

2). Length - meter

3). Time - Seconds

4). Electric Current - Ampere

5). Amount of substance - Moles

6). Intensity of light - Candela

7). Temperature - Kelvin

Thus SI base unit of temperature is Kelvin.

b is the correct

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
