a. to help you make a better decision.

Bayes' theorem is used to update probabilities (your beliefs) when new evidence arrives. Gathering more information reduces uncertainty and lets you compute a more accurate posterior probability, which leads to better decisions. (Option b can be true in specific cases — you might collect data to estimate a missing likelihood or prior — but the general reason is to improve your decision by refining your probabilities. Option c is too absolute.)
