Explanation:

- Totipotency (Option 3): This is the ability of a single cell to develop into a complete, fertile adult organism. It can generate all cell types, including both embryonic and extra-embryonic tissues.

- Cloning (Option 1): This is the process of producing genetically identical individuals from a single organism. It doesn't inherently refer to a single cell's ability to generate an organism.

- Pluripotency (Option 2): This refers to the ability of a cell to develop into almost all cell types but not extra-embryonic tissues. It can't form a complete organism on its own.

- Mutation (Option 4): This is a change in DNA sequence, not directly involved in the ability of a cell to develop into an organism.
