It's B because 1 Litre is 1000 millimeteres
If 40% of students prefer keyboarding, 40/100*40=16 students like it best. If the remaining students prefer English, then 40-16=24 students like English best. Since 24 is more than 16, most students prefer English.
We can say that the other number is even or it is 0.
B
Hope this helps :)
Can I have Brainliest please
