(2) Before the date of enactment of the Education for All Handicapped Children Act of 1975 (Public Law 94-142), the educational needs of millions of children with disabilities were not being fully met because--
(A) the children did not receive appropriate educational services;
(B) the children were excluded entirely from the public school system and from being educated with their peers;
(C) undiagnosed disabilities prevented the children from having a successful educational experience; or
(D) a lack of adequate resources within the public school system forced families to find services outside the public school system.
