Answer:

220

Step-by-step explanation:

Given that the freshman class has 160 students.

Each freshman must write three reports from a list of 12 novels that the teacher has assigned them to read

Here order does not matter.  Hence combinations can be used.

No of available options  = 12

No to be selected =3

Possible number of ways = ways of selecting 3 from 12 where order does not matter

= 12C3\\=\frac{12(11)(10)}{6} \\=220

Option B is right answer.
