Which of the following options is recommended?
A . import org.apache.felix.scr.annotations.Component; @Component(label = "My configuration", metatype = true, factory= true)
B. import org.osgi.service.component.annotations.Component; @Component(service = ConfigurationFactory.class)
C. import org.osgi.service.metatype.annotations.AttributeDefinition; import org.osgi.service.metatype.annotations.ObjectClassDefinition; @ObjectClassDefinition(name = "My configuration")
D. @Component(service = ConfigurationFactory.class) @Designate(ocd = ConfigurationFactorylmpl.Config.class, factory=true)

Answer: D

Explanation:

The @Component(service = ConfigurationFactory.class) @Designate(ocd = ConfigurationFactorylmpl.Config.class,factory=true) option is recommended for creating a multi-tenancy configuration and binding multiple configurations to it. This option uses the OSGi R6 annotations to define a component that provides a service of type ConfigurationFactory and designates a class that contains the configuration properties. The factory=true attribute indicates that multiple configurations can be created for this component.
