Without more specific information, it is not possible to determine which mutation would be most likely to have a harmful effect on an organism. The effects of a mutation depend on various factors such as the location and function of the gene, the specific amino acid sequence affected, and the overall genetic background of the organism. In some cases, a substitution of a single nucleotide may lead to a non-functional protein, while in other cases, it may have no effect or even a beneficial effect. Similarly, the consequences of a deletion of three bases would depend on the specific sequence affected and its functional significance.
