Questions: When investments have cash flows with little risk, valuations are a. unpredictable. b. relatively easy. c. distinguishable. d. relatively difficult.

The answer is the second one (or B): relatively easy.

Explanation for each option: a. Unpredictable: This is incorrect because low-risk cash flows are generally more predictable, making valuations more straightforward. b. Relatively easy: This is correct because when cash flows have little risk, they are more predictable and stable, making the process of valuation simpler and more reliable. c. Distinguishable: This is incorrect because while low-risk cash flows may be distinguishable, this term does not directly relate to the ease of valuation. d. Relatively difficult: This is incorrect because low-risk cash flows reduce uncertainty, making the valuation process less difficult.

Summary: When investments have cash flows with little risk, valuations are relatively easy.
