What are the dimensions of force?

[alingy1]

I'm doing practice problems:
I am confronted to this:
The dimensions of force are (x means “multiplied by”):
(a) kg.m.s-2,
(b) mass x length x (time)-2,
(c) Newtons,
(d) mass x acceleration.

I need someone to back up my reasoning.

It says dimensions, so I'm going towards (b) because (a) and (c) are units and, as for (d), acceleration is not a dimension.

That would be my answer too, for the same reasons you mentioned.
