Which of the following is typically the best person to choose as a recommender?

a. a fourth-grade teacher
b. a ninth-grade or freshman-year teacher
c. an eleventh-grade or junior-year teacher
d. a middle school teache

C.An eleventh-grade or junior-year teacher

It'll be the teacher that'll know you more up-to-date than the other ones, which you had when you were younger.

Hey there!

For recommendation letters, I would say that you should go with the teacher who has:

1. most recently known and worked with you 
2. has experienced you at your most intelligent
3. has worked with you with the hardest material you've studied so far

Intelligence naturally grows with each passing grade. As you start to work on relatively harder material, your knowledge is bound to grow. Also, whoever you've worked with most recently will be able to recall you (and your abilities, talents, traits, etc.) much easier, meaning that they will have more to base their recommendation on. 

Your answer will be C. 

Hope this helped you out! :-)
