Explanation:

• Option A: Surveying the first 25 members on a particular weekday may introduce bias. Members present on that specific weekday might not be representative of all members. For example, some members might only visit on weekends.
• Option B: Randomly surveying 25 members of her makerspace gives each member an equal chance of being selected. This helps to avoid bias and makes the sample more likely to be representative of the entire population of members.
• Option C: Surveying members of a different makerspace is not relevant. The question is about her members' opinions, not another makerspace's members.
• Option D: Creating a poll on social media and using the first 25 responses may have bias. People who respond first might have a particular interest or availability that is not representative of all members. Also, not all members may use the social media platform where the poll is created.

Answer:

B. Surveying 25 members of her makerspace at random
