Answer:
D alpha particles
Explanation:
Radioactive U-238 will decay into Thorium -232 by emitting alpha particles in the process of nuclear fission.
Nuclear fission is the radioactive decay process in which a heavy nucleus spontaneously disintegrates into two lighter ones and several other particles with a large release of energy.
U-238 → Th-232 + alpha particles + 2 neutrons + energy
This way the mass and atomic numbers are conserved;

120 grams of NaOH means 3 Moles of NaOH because 40 grams (Molecular Weight in grams) is one mole of NaOH.
Each mole of any substance contain Avogadro’s number of molecules ie., 6.022 x (10 to the power 23).
Hence 3 Moles of NaOH contain 3 times of Avogadro’s number of molecules ie., 3 x 6.022 x (10 to the power 23)
If its oxidised, water and carbon dioxide is formed.
