Answer:
The correct answer choice is B. √24
Explanation:
Since √20 is approximately 4.472, It would have to go a little less than halfway between 4 and 5. While √27 is 5.196, it would be barely past the number 5, and the same thing applies to √26 (which is 5.099) except closer to 5 than √27.
This leaves the only answer choice B. √24 being the correct result
