Option 1 is correct. This option matches each distinguished lady with the correct organization or industry she is associated with.

In detail:

A. Amrita is not associated with the National Dairy Development Board, thus eliminating options 2 and 4.

B. Anu Aga is indeed the previous chairperson of Thermax Limited, verifying option 1.

C. Mallika Srinivasan is the CEO of Tractors and Farm Equipment Limited, further verifying the correctness of option 1.

D. Priya Paul is the Chairperson of the Park Hotels group, again confirming the accuracy of option 1.

Option 2, 3 and 4 incorrectly match the ladies with the organisations or industries they are associated with. For example, option 2 incorrectly matches Amrita with Park Hotels, Anu Aga correctly with Thermax, Mallika Srinivasan incorrectly with National Dairy Development Board and Priya Paul incorrectly with Tractors and Farm Equipment Limited.
