## Step 1: In beta decay, a neutron in the nucleus of an atom is converted into a proton, an electron, and an electron antineutrino. The electron and the antineutrino are ejected from the nucleus, while the proton remains in the nucleus, increasing the atomic number by 1.## Step 2:In this case, the original atom is iodine-131, which has an atomic number of 53. After beta decay, the atomic number increases by 1, so the resulting atom should have an atomic number of 54.## Step 3:Looking at the options, only option D, tellurium-131, has an atomic number of 54. Therefore, it is the correct answer.
