Solution

Para responder a la pregunta sobre cuál método se usa comúnmente para ejecutar consultas SQL en JDBC, vamos a analizar cada una de las opciones:

a. executeQuery(): Este método se utiliza para ejecutar sentencias SQL que devuelven un conjunto de resultados, típicamente una consulta SELECT.

b. executeUpdate(): Este método se usa para ejecutar sentencias SQL que modifican la base de datos, como INSERT, UPDATE o DELETE. No se utiliza para consultas que devuelven datos.

c. execute(): Este método puede ejecutar cualquier tipo de sentencia SQL, pero no es específico para consultas que devuelven resultados. Puede ser usado para sentencias SELECT, INSERT, UPDATE o DELETE, pero es menos común para consultas que devuelven datos.

d. runQuery(): Este método no es parte de la API JDBC estándar.

Por lo tanto, la respuesta correcta es:

a. executeQuery()
