Explanation:

- In the third bi-monthly monetary policy review of 2019-20, the Reserve Bank of India (RBI) analyzed inflation trends.

- Option 1: 4 per cent - Generally, this level is comfortable for India's inflation target.

- Option 2: 5 per cent - Slightly above the mid-point of RBI's target range but manageable.

- Option 3: 6 per cent - Often considered the upper threshold of RBI's target range.

- Option 4: 7 per cent - Typically considered high and a cause for concern regarding purchasing power.

- Option 5: None of the above - Indicates a prediction outside these presented values.

The correct option is 6 per cent (Option 3) as it matches the upper bound concern indicated by RBI.
