To determine in which process a mutation is first able to develop, we need to consider what each process entails:
- **Transcription (A)**: This is the process where DNA is transcribed into mRNA. If a mutation occurs in the DNA during this stage, it can be transcribed into mRNA, potentially affecting the protein produced.
- **Post-Transcription (B)**: This refers to the processes that occur after transcription, such as mRNA splicing, capping, and polyadenylation. Mutations that affect splicing or mRNA stability can have consequences, but they would not be the first step for a mutation to appear.
- **Translation (C)**: This is where mRNA is translated into a protein. A mutation that changes the codon in the mRNA could lead to an altered protein but would come after the mutation in the DNA.
- **Post-Translation (D)**: This refers to modifications made to proteins after their synthesis. Mutations cannot develop at this stage since they pertain to the protein level, not the genetic level.
Considering the above explanations, the mutation is first able to develop during the **transcription** process, where the change in DNA sequence would first be seen in the RNA produced.
So, the correct response is:
**A. transcription**
