EB1 has multiple functions, including promoting microtubule growth by enhancing polymerization at the (+)end, serving as a binding platform for other plus-end tracking proteins to "hitchhike" onto the growing microtubule, and binding further back from the blunt end of microtubules. Therefore, all of the statements given in A, B, and C are true about EB1.
