I think that the best answer is "c. an incentive to bring their ideas to market" - you can see that through the statement of "<span>the opportunity to profit from their ideas"- an opportunity to profit is an incentive to work and in the case of the creators - to bring their ideas to market.
However, an opportunity to profit is not a guarantee that one will profit - so for example option a) is wrong. </span>
I give one, for example: when I was travelling on Malta, I found a lot of Roman remains: catacombs, mosaics, a remain of a Roman house.
Malta is an island so they must have used sea travel to get there.
Be specific, what section?
Probably the @, which is called the "at sign" by most.
Good luck!

An epigraph is a quotation placed at the beginning of a work or a chapter.<span>"Self-Reliance" was published in 1841 in a collection entitled Essays<span>. In 1844, Emerson published a second collection. The <span>essay urges readers to trust their own intuition and common sense rather than automatically following popular opinion </span></span></span>
The epigraphs to Emerson's essay "self-reliance" all somehow deal with independence and self-reliance.
