The correct option is B A strong centre
Indian Constitution is quasi-federal i.e., it comprises of a strong centre and state wherein parliament is empowered to legislate on subjects not specifically mentioned in Constitution (residuary subjects). Where state and centre both legislate on the same subject the central law shall prevail. During an emergency, it acquires unitary form. Due to this reason, it is called "Quasi federal". So, the Constitution made arrangements for the strong centre.
