I know that D is correct, but I think A also correct. Maybe someone can brief me why only D is correct?

The tag library descriptor for a tag library must be kept in META-INF/taglib.tld, if the tag library is packaged in a jar file.

I think it is not correct because if it is inside a jar it should be META-INF/jar/taglib.tld

Please correct me if iam wrong..

TLD can have any name whose extension is ".tld", and must put under META-INF (or subdirectory of it) when packaged in a JAR file. So it is not restricted to only one taglib.tld.
