The correct answer is option 3, which is six. Chhattisgarh is a state located in central India and is surrounded by six other states.

To understand why option 3 is the correct answer, let`s examine the geography of Chhattisgarh. Chhattisgarh is bordered by Madhya Pradesh to the northwest, Uttar Pradesh to the north, Jharkhand and Odisha to the northeast, Telangana to the south, and Maharashtra to the southwest. These six states give us a total of six states surrounding Chhattisgarh.

Option 1, which states that Chhattisgarh is surrounded by four states, is not correct as it does not account for all the neighboring states correctly.

Option 2, which states that Chhattisgarh is surrounded by five states, is also incorrect as it does not include Maharashtra as one of the surrounding states.

Option 4, which states that Chhattisgarh is surrounded by seven states, is not correct either as it includes an additional state that is not a direct neighbor of Chhattisgarh.

Therefore, the correct answer is option 3, as Chhattisgarh is surrounded by six states.
