Consider the pushdown automaton with the following transition rules:

(q,0,Z₀) = {(q,XZ₀)}

(q,0,X) = {(q,XX)}

(q,1,X) = {(q,X)}

(q,,X) = {(p,)}

(p,,X) = {(p,)}

(p,1,X) = {(p,XX)}

(p,1,Z₀) = {(p,)}

From the ID (p,1101,XXZ₀), which of the following ID's can NOT be reached?

a)(p,1101,Z₀) b)(q,01,XXZ₀) c)(p,01,XXXZ₀) d)(p,01,XXXXZ₀)
