In the disintegration of a radioactive element, `alpha`- and `beta`-particles are evolved from the nucleus. `._(0)n^(1) rarr ._(1)H^(1) + ._(-1)e^(0) +` Antineutrino + Energy `4 ._(1)H^(1) rarr ._(2)He^(4) + 2 ._(+1)e^(0) +` Energy Then, emission of these particles changes the nuclear configuration and results into a daughter nuclide. Emission of an `alpha`-particles results into a daughter element having atomic number lowered by 2 and mass number by 4, on the other hand, emission of a `beta`-particle yields an element having atomic number raised by 1. Select the correct statements among the following:A. Emission of a `beta`-particle results into an isobar of parent element.B. Emission of `alpha`-particles results into an isodiapher of parent element.C. Emission of one `alpha`-and two `beta`-particles results into an isotope of the parent element.D. Emission of `gamma`-radiations may yield a nuclear isomer.
