Explanation:

- Totipotency (Option 3): This is the ability of a single cell to develop into a complete, fertile adult individual. It can also form all cell types, including extra-embryonic tissues such as the placenta in mammals.

- Cloning (Option 1): This is a process of creating an identical copy of an organism. It's not related to a single cell's inherent ability but rather an artificial method.

- Pluripotency (Option 2): This refers to a cell's ability to develop into almost any cell type, but not a complete organism. It's more limited than totipotency.

- Mutation (Option 4): This is a change in DNA sequence. It doesn't relate to the cell's ability to develop into a new organism.
