C not sure um take a guess
Answer:
Dr. Ingram conducted an C. experimental study.
Explanation:
An experimental study is that in which the variables are in direct control of the researcher. He/she is in control of <em>changing or adjusting</em> them in order to reach an outcome.
Dr. Ingram <em>varied the imageability of items </em>on a list to measure the participants' recalling abilities. He is conducting an experimental study.
Let's see why the other options are not valid in this case:
- A correlational study tries to find correlations between 2 or more variables.
- In a naturalistic study the researcher observes a certain phenomenon.
- An observational study just centers on observing, there is no manipulation of variables.

Option: C
Explanation:
It is in the norms that in same type of research, both the researchers need to maintain some ethics and rules that if they do same type of experiments and use same materials they should acknowledge the other or take permission before doing that.
Here researcher A is conducting research on emphysema using bio specimen from human subjects and researcher B is doing research on lung cancer. He also need bio specimen. But as it is mentioned in the consent form that specimen is de identified so no problem for researcher B in using same specimen like researcher A.
