The correct answer is D) all of the above.

Merchants decided to use money instead of bartering because money was easier to carry and handle than goods, money was accepted anywhere and could be used again, it was difficult to exchange the exact value of goods in barter.

Merchants realized that there were many benefits to changing to the monetary system when trading their goods. The reasons mentioned above were enough to opt for money instead of bartering. They considered this new system to be fairer in that money represented more equity in trading than in bartering because some times the value of things exchanged was not the same.

pepin the short[a] (german: pippin der kurze, french: pépin le bref, c. 714 – 24 september 768) was the king of the franks from 751 until his death. he was the first of the carolingians to become king.[b][2]

the younger son of the frankish prince charles martel and his wife rotrude, pepin's upbringing was distinguished by the ecclesiastical education he had received from the monks of st. denis. succeeding his father as the mayor of the palace in 741, pepin reigned over francia jointly with his elder brother carloman. pepin ruled in neustria, burgundy, and provence, while his brother carloman established himself in austrasia, alemannia and thuringia. the brothers were active in suppressing revolts led by the bavarians, aquitanians, saxons, and the alemanni in the early years of their reign. in 743, they ended the frankish interregnum by choosing childeric iii, who was to be the last merovingian monarch, as figurehead king of the franks.
