The Correct Option is B, C, D

Solution and Explanation

The problem involves determining which refill configurations allow complete use of the mosquito repellent by aligning a red mark on the refill with a corresponding mark on the machine. Let's analyze how each option functions:

Analysis:

To ensure all the liquid is consumed, the positioning of the refill bottle needs to properly align with the red mark on the socket. This alignment allows the liquid to flow freely without obstruction, ensuring complete usage.

  1. Refill 1

    Refill 1: Examination reveals potential misalignment issues; thus, not all liquid can be used.

  2. Refill 2

    Refill 2: The configuration appears to correctly align the red marks, facilitating complete liquid use.

  3. Refill 3

    Refill 3: Proper alignment is possible with this configuration, enabling full liquid consumption.

  4. Refill 4

    Refill 4: Designed to align correctly, allowing for complete use of the liquid repellent.

Conclusion: The refills that enable the liquid to be entirely used (Refill 2, Refill 3, and Refill 4) successfully align the refill's red mark with the machine's equivalent mark. Therefore, these configurations are correct.
