Choose the address that is the same as the one given below. Flat No. 12B, Sunrise Towers,Park Street, Kolkata,West Bengal - 700016

Correct — D.
Rule: find the part that differs across the options, then check it against the original.

Flat No. 12B, Sunrise Towers, Park Street, Kolkata and 700016 are the same in all four options, so they decide nothing.
The state is what changes. The original says West Bengal.

Option (d) alone keeps West Bengal → option (d).

Why the others are wrong

• (a)
  Flat No. 12B, Sunrise Towers, Park Street, Kolkata, Bihar - 700016 — Bihar stands where the original has West Bengal. The flat, building, street, city and PIN all match, so the state name alone rules it out.
• (b)
  Flat No. 12B, Sunrise Towers, Park Street, Kolkata, Jharkhand - 700016 — Jharkhand replaces West Bengal. Every other part is copied exactly, which is what makes it look right at a glance.
• (c)
  Flat No. 12B, Sunrise Towers, Park Street, Kolkata, Odisha - 700016 — Odisha replaces West Bengal. The task is an exact copy, so a different state is a mismatch however close the rest is.

Address matching is a proof-reading task. Split the original at its commas and compare each part with the same part of every option, dropping an option at its first mismatch.

Here the flat number, building, street, city and PIN are identical in all four options, so the item turns on the state name. Find the part that varies, check it against the original, and you are done.

Key facts

• Kolkata is the capital of West Bengal.
• Indian PIN codes beginning with 7 include West Bengal, Odisha and the North-Eastern states.
• A part that matches in all four options cannot decide the answer.

Common traps

• Comparing the options with each other instead of with the original address
• Treating the missing spaces after commas in the original as the difference to hunt for
