The following sentence has been divided into five segments. The first segment has no error. Select the option that has the segment with the grammatical error.
Due to the pandemic, / the prices of / medicines increased / every day since / last December.

Correct option is B

Option (b) contains an error.
Explanation:
· The phrase "medicines increased" is incorrect because "since" refers to a specific point in time and should be followed by the present perfect tense (e.g., "have increased").

Grammatical Rule:
· Use the present perfect tense with "since" to describe an action that started at a specific time in the past and continues up to the present.
Example:
