The correct answer is Option (4) → Finding a water tap inscribed as open to all castes and religions

(A) Someone digs up a twentieth century city. — Correct. The poem opens in the future, when someone digs up a twentieth century city. The digger then finds an inscription: 'This water tap is open to all castes and religions'.

(B) Wonders whether that society was divided. — Correct. The inscription makes the digger wonder whether that society was divided, with some high and others low. A tap needs such a notice only where castes are kept apart.

(C) Decides the city deserved burying. — Correct. The digger decides the city deserved burying. The poet mocks the machine age as a Stone Age in the twentieth century.

Note: The missing step is the find of a water tap open to all castes and religions. A notice of equal access tells the digger that unequal access was the normal rule.
