{'fission': [0, 0, 0, 1], 'smaller nuclei': [0, 0, 0, 1], 'heavier nuclei': [0, 0, 0, 1], 'higher nuclei': [0, 0, 0, 1], 'cell division': [2, 0, 0, 0], 'unicellular organism': [1, 0, 0, 0], 'transformation': [0, 0, 0, 4], 'creation': [0, 0, 0, 1]}

The correct answer is option 3: 1 and 2 only.

Option 1 states that fission is related to the creation of new individuals by cell division in unicellular organisms. This statement is incorrect. The process described in option 1 is actually called binary fission, which is a form of asexual reproduction in which a single organism divides into two identical offspring.

Option 2 states that fission is related to the transformation of heavier nuclei into smaller nuclei. This statement is correct. Fission is a nuclear reaction in which the nucleus of an atom splits into two smaller nuclei, releasing a large amount of energy. This process is used in nuclear power plants and nuclear weapons.

Option 3 states that fission is related to the creation of a heavier nucleus by combining two higher nuclei. This statement is incorrect. The process described in option 3 is actually called fusion, where two smaller nuclei combine to form a larger nucleus.

Therefore, the correct statement about fission is that it is related to the transformation of heavier nuclei into smaller nuclei, making option 3 the correct answer.
