My corporation made cash sales to customers. Which effect does it have on the accounting equation?

Question

a. liabilities increase and owner's equity increase
b.assets increase and assets decrease
c.assets increase and liabilities increase
d.assets decrease and liabilities decrease

Answer 1

The accounting equation:
Assets = Liabilities + Owner's Equity

My corporation made cash sales to customers.
Your entry would be:
Dr Cash
Cr Sales

so Assets and Owner's equity should both increase. It's odd that it's not one of the choices.

Answer 2

None of the above!!!!!

It would be: increase an asset and increase stock holders equity.
