I think the ans is D.

For these kind of questions i find it helpful to actually write out the relations. In this case:
1. Merco>Nolen
2. Olean>Potter
3. Quales>Potter
4. Nolen = Quales

Simmilarly C can be written as Olean > Nolen, which NEED not be true. Thus C is out.

On the other hand, D can be written as Merco>Potter. This is true from 1, 3 and 4. Thus D is the right answer.

Yes D, because we have a factual info on this one....

We know that Merco > Nolen,
We also know that Nolen = Quarles
And Quarles is > Potter, so we could say that Nollen > Potter
So if Nollen was in business for more years than Potter, Merco is definetely older company than Potter, since Merco is even older than Nolen....

Not C because we cannot confirm that. We only know that Nolen>Potter and Olean>Potter... we do not have data on Nolen relation to Olean....

Best is to draw a small chart to compare.
