Explanation:

Question 11

A conflict of interest in research occurs when personal/financial interests could bias results. Option a is wrong (no funding isn't conflict), b is wrong (no interest isn't conflict), c is wrong (transparency is good, not conflict). So d is correct.

Conceptual models focus on specific aspects, oversimplifying. Physical models are tangible, computer models use software, mathematical models use equations—none oversimplify like conceptual. So d is correct.

A hypothesis is a testable prediction. a is wrong (conclusion is after testing), c is wrong (summary is literature review), d is wrong (description is observation). So b is correct.

Answer:

d. When personal or financial interests could bias research results
