Question $7.$

What does the following transition function mean$/$do$?$ Choose the most appropriate option from the list below.

$(q,[0,1])=(p,(1,R),(0,L))$

a$)$ It's a transition function for an NTM$.$ In state q$,$ with either $0$ or $1$ under its head, it will transition to state $p,$ and non$-$deterministically choose to either write $1$ on the tape and move right or write $0$ on the tape and move left.

b$)$ It's a transition function for a TM with two tapes. In state $q,$ when it has $0$ under its head of tape $1$ and $1$ under the head of tape $2,$ it will write $1$ on the first tape and move right and it will write $0$ on the second tape and move left when transitioning into state $p.$

c$)$ It's a transition function for a multi$-$track TM with storage. When in state q with $0$ on the first track and $1$ on the second track, it will transition to state q$,$ writing $1$ on the first track and moving that head to the right and writing $0$ on the second track and moving the other head to the left.

d$)$ This is an invalid transition function.
