Explanation:

Correct Answer is (c).The statement states that the annual inflation rate has been low. It starts with 'although' which implies the next statement should be in contradiction with the one given.
Statement I: Although annual inflation rate has hovered on the lower side of 6%, it has steadiliy been trending upwards since 2015.
The first statement says inflation has been rising since 2015. This means that although the annual inflation is lower this year yet, as compared to the years since 2015, it has risen. This makes sense and is correct.
Statement II: Although annual inflation rate has hovered on the lower side of 6%, the Central Bank considers those readings to be consistent with its goal of 5-7%.
Statement II says the Central Bank considers those readings to be consistent with its goal of 5-7%.This also looks consistent with the context.
Statement III: Although annual inflation rate has hovered on the lower side of 6%, growth forecast has been reduced to 6% from 6.3%.
The last statement, however, does not match with the original statement. When inflation is low, growth slows down. So both the statements are in agreement with each other rather than contradiction.
Hence, option C is correct.
