The correct answer is a. BCNF is more restrictive than 3NF.

Here's why:

1. BCNF and 3NF are both forms of database normalization that aim to reduce redundancy and dependency in relational databases.

2. 3NF is a less strict form of normalization that allows some redundancy in the database to maintain its usability. It requires that all non-key attributes be functionally dependent on the primary key.

3. BCNF, on the other hand, is a stricter form of normalization. It requires every determinant to be a candidate key. This means that there can be no non-trivial functional dependencies of attributes on something other than a superset of a candidate key.

4. Because BCNF is stricter, it allows fewer update anomalies than 3NF. Update anomalies are inconsistencies that can occur when data is inserted, updated, or deleted.

So, BCNF is more restrictive than 3NF (option a), and it allows fewer update anomalies than 3NF (option d). It does not allow more redundancy than 3NF (option b), and it is not less restrictive than 3NF (option c).
