If a particle of a link has a velocity when changes both in magnitude and direction at any instant, then

[A].	It must have only unidirectional acceleration	[B].	It must have two components of acceleration e.g. centripetal, and tangential
[C].	It must have three components of acceleration e.g. centripetal centrifugal and tangential	[D].	It must have three components of acceleration e.g. centripetal, centrifugal and gravitational
[E].	It must have four components of acceleration e.g. centripetal, centrifugal gravitational and tangential
