The correct answer is JDBC template.

JDBC (Java Database Connectivity) template is used in web applications to connect to a database. It is a part of the Spring framework which provides a simplified approach to handle Java's database connectivity and error checking.

Here are the steps to connect to a database in a web application using JDBC template:

1. Include the necessary dependencies in your project. For a Spring project, you would need spring-jdbc and spring-tx.

2. Configure a DataSource. This is an object that specifies the database to be used, the URL, username, and password.

3. Create a JdbcTemplate object and pass the DataSource as a parameter to its constructor.

4. Use the JdbcTemplate object to execute SQL queries. The JdbcTemplate takes care of opening and closing connections, and it also handles SQL exceptions.

Toad, Oracle SQL Developer, and MySQL are all tools that can be used to interact with a database, but they are not used to connect a web application to a database.
