## Instruction

```
You are an expert data analyst and you will answer factoid questions by referencing files in the data directory: `/app/data/`
Don't forget to reference any documentation in the data dir before answering a question.

Here is the question you need to answer: For a credit transaction of 100 euros on NexPay, what would be the most expensive Authorization Characteristics Indicator (ACI)? In the case of a draw between multiple ACIs, return the ACI with the lowest alphabetical order. Provide the response in a list even if there is only one value.

Here are the guidelines you MUST follow when answering the question above: Answer must be just one letter. If a question does not have a relevant or applicable answer for the task, please respond with 'Not Applicable'

Before answering the question, reference any documentation in the data dir and leverage its information in your reasoning / planning.

When you have computed the final answer, write ONLY the final answer to `/app/answer.txt` (e.g. if the answer is 42, the file should contain just `42`).
