Explanation

timorous, precarious, and suspect

Because the stress tests are supposed to reassure the investors, the first blank must describe someone in need of reassurance, so something like scared or nervous would make sense; timorous is the best match.

The second blank describes financial institutions that are distinguished from reliable ones, so the word for that blank should contrast with reliable. Of
the choices, precarious offers the best contrast.

Finally, the results are reported with a lack of candor, so the test results should be dishonest or unreliable. Suspect is the best choice.

Hence option C, D and H are correct!
