A radioactive decay follows the conservation of charge and the conservation of mass.
In an alpha decay a parents nuclei converts into daughter nuclei with the emission of the helium nuclei ( alpha particle ). The general reaction of an alpha decay is given below:
${}_{Z}^{A}X{=}_{Z-2}^{A-4}Y{+}_{2}^{4}He$
here, X is the parent nuclei and Y is the daughter nuclei.
Taking above reaction into account the alpha decay of ${}_{93}^{241}Am$ will be:${}_{93}^{241}Am{=}_{91}^{237}Np{+}_{2}^{4}He$
The daughter nuclei is ${}_{91}^{237}Np$
Hence, option 5 is correct.
