I believe the answer is <span> A. We didn't have enough potatoes for dinner, so we served rice instead
A sentence could be considered as complex sentence if it has at least one independent clause and a minimum of one dependent clause.
</span><span><em>We didn't have enough potatoes for dinner >> </em>Independent
<em>, so we served rice instead </em>>>> Dependent</span>
What do you want us to answer?
