D Correct answer
Explanation

Replacing Perl and PHP scripts which contain both presentation and business logic requires a multi-layered J2EE architecture. JSP and Servlets handle the dynamic web presentation layer, while Enterprise JavaBeans (EJBs) manage the business logic and transaction processing, communicating with the database. Using JSPs/Servlets alone would lack a dedicated business logic tier.
