Correct Answer: Pakistan

Solution : The correct answer is (b) Pakistan.

As of June 2023, Pakistan has the highest inflation rate among India, Pakistan, and China. The inflation rate in Pakistan is 19.9 %, followed by India at 5.1 % and China at 2.0 %.

The high inflation rate in Pakistan is due to a number of factors, including rising food and energy prices, the depreciation of the Pakistani rupee, and the government's decision to cut fuel subsidies.

It is important to note that inflation rates can fluctuate significantly over time, so it is possible that another country could have the highest inflation rate in the future.
