Correct answer: (b) Basti
Explanation
- A
Faizabad
(a) Faizabad. Purvanchal Expressway is aligned through the Ayodhya/Faizabad belt on the Lucknow–Ghazipur run. Faizabad is on the corridor, so it is not the city the road will skip.
- B
Basti
(b) Basti. The expressway runs Lucknow–Barabanki–Ayodhya–Ambedkar Nagar–Azamgarh–Mau–Ghazipur and does not take the northern Basti loop. That stored skip is the official key. Basti sits on NH stretches toward Gorakhpur, not on this greenfield alignment.
- C
Azamgarh
(c) Azamgarh. Azamgarh is a named district on the Purvanchal Expressway. The road does pass it, so this is not the exception.
- D
Mau
(d) Mau. Mau is on the eastern stretch toward Ghazipur. It is served, not omitted.
Summary. Official key is (b) Basti. Purvanchal Expressway links Lucknow to Ghazipur through Faizabad/Ayodhya, Azamgarh and Mau. Basti is the listed city that does not lie on that alignment. Neighbouring nodes are Barabanki, Ambedkar Nagar and Ghazipur. Do not confuse the Gorakhpur–Basti national highway with this expressway.
