URGENTTT!!!

Consider the grammar, G:

S aAa | bBb

A aAa | b

B bBb | a

Mark the correct Chomsky Normal Form Grammar(s) that will derive L(G). Incorrect marks will reduce your grade.

a)		S PQ | RT, A PQ | b, B RT | a, P QA, R TB, Q a, T b
b)		S PQ | RT | a | b, P AP | b, Q QA | b, R BR | a, T TB | a
c)		S aA | bB, A Aa | b, B Bb | a
d)		S PQ | RT, A PQ | b, B RT | a, Q AP, T BR, P a, R b
