Step 1: Understand the question.
The question asks which of the four Harappan (Indus Valley) sites lie in the modern state of Haryana. We must check each site one by one and then pick the option that lists exactly the right ones.
Step 2: Check site A, Bhirrana.
Bhirrana is a village in the Fatehabad district of Haryana, on the dry bed of the old Saraswati-Ghaggar-Hakra system. It has early Harappan and mature Harappan layers. So A belongs to Haryana.
Step 3: Check site B, Kalibangan.
Kalibangan is in the Hanumangarh district of Rajasthan, on the banks of the dry Ghaggar. It is famous for its ploughed field and fire altars. It is not in Haryana. So B does not belong.
Step 4: Check site C, Rakhigarhi.
Rakhigarhi is in the Hisar district of Haryana. It is one of the largest Harappan towns known, and the ancient DNA study came from here. So C belongs to Haryana.
Step 5: Check site D, Farmana.
Farmana is in the Rohtak district of Haryana. It is known for a large cemetery and house plans of the mature Harappan period. So D belongs to Haryana.
Step 6: Match with the options.
The correct set is A, C and D, and B must be left out. Option 1 says A, C and D only. Option 2 wrongly includes B and drops C. Option 3 includes B, so it is wrong. Option 4 drops A and includes B, so it is wrong.
Final Answer:
Bhirrana, Rakhigarhi and Farmana are in Haryana, while Kalibangan is in Rajasthan. This matches option 1.
\[ \boxed{\text{A, C and D only}} \]
