What is Dhing Express?

1. A

   Train between Dhing and Kolkata

   There is no famous passenger train nicknamed Dhing Express as the answer to this current-affairs item. Dhing is Hima Das’s hometown in Assam, not the identity of the phrase here. This option is not the key.

2. B

   Nickname of Hima Das

   Hima Das, the Assamese sprinter from Dhing, Nagaon, is popularly called Dhing Express after her 2018 world junior gold and later senior medals. The nickname is hers. This option is the official key.

3. C

   Express way between Palwal and Kundli

   The Palwal–Kundli stretch is part of the Eastern Peripheral Expressway around Delhi, not called Dhing Express. This option is therefore wrong.

4. D

   Popular Magazine

   Dhing Express is not the title of a popular magazine in this question’s sense. This option is not the key.

Summary. Official key is (b) Nickname of Hima Das. In 2018 she became the first Indian to win gold at a world track event, the IAAF World U20 400 metres. Media tagged her Dhing Express after her Assam town. It is not a train, an expressway or a magazine. Only (b) is correct.
