Salaries ___ since she became the CEO of our company.a) had increasedb) increasedc) have increasedd) are increasing

To determine the correct answer for the sentence completion, we need to analyze the structure of the sentence in relation to the timeline and grammatical tense.

Step 1: Analyze the Sentence

The sentence indicates a change in salaries starting from a point in the past (when she became CEO) up to the present. This suggests that a present perfect tense might be appropriate.

Step 2: Examine Each Option

1. a) had increased - This is past perfect tense, indicating a completed action before another past action, which doesn't fit because the sentence discusses a continuation up to now.

2. b) increased - This is simple past tense, implying that the action is no longer ongoing, which contradicts the context.

3. c) have increased - This is present perfect tense, indicating that the increases started in the past and continue to the present. This fits the context perfectly.

4. d) are increasing - This implies an action that is currently happening but does not fit well with the indication of a change since a specific past point.

Step 3: Select the Best Option

Given the analysis, the most suitable choice is c) have increased as it effectively communicates that the increases began in the past and are still relevant now.

Final Answer

c) have increased
