Among the job titles listed, "architec" is the one that may be least associated directly with a career primarily focused on mathematics, although math is certainly involved in architecture.
However, both "drafter" (who often uses math in technical drawing and design) and "statistician" (who works directly with data and requires strong mathematical skills) have more direct connections to math.
Lastly, "geneticist" deals more with biological sciences, but can also involve statistics and mathematical modeling.
In summary, while all of these roles incorporate math to some extent, “architect” may be perceived as not being purely a math career.
But if strictly speaking, geneticist might be the best answer to your question as it's more focused on biology, whereas the others are more involved with mathematics.
So, the correct answer would be geneticist if you are looking for the least math-related career. If the question is considering math involvement, then "architect" due to its design aspect over math emphasis could also work.
