_____ consists of a set of interfaces and classes written in the Java programming language.a)JDBC APIb)Embedded SQLc)JDBC Architectured)Connection Pools

The answer to this question is (a) JDBC API.

Explanation

JDBC (Java Database Connectivity) API is a standard Java API that allows Java applications to interact with databases. It consists of a set of interfaces and classes that provide methods for querying and updating data in a database. Here's a brief overview of the options:

1. JDBC API: A framework in Java to connect and manipulate databases.
2. Embedded SQL: Refers to SQL statements embedded in programming code.
3. JDBC Architecture: Describes the design and structure of the JDBC API, not a set of interfaces or classes itself.
4. Connection Pools: Refers to a cache of database connections maintained to improve performance, but not specifically a set of interfaces or classes in Java.

Thus, the JDBC API is indeed the correct choice as it directly consists of the specified features.
