Concept:A factor is a mercantile agent with possession of goods, while a broker only negotiates transactions without taking possession.
Explanation:The "former" in the question refers to the factor.
A factor is entrusted with actual possession or control of the goods he sells.
Because of this possession and authority, a factor has a lien on the goods for his commission and expenses.
A broker, by contrast, does not have possession of the goods and therefore does not enjoy such a lien.
Thus, among the given options, the factor differs from the broker because the factor has a lien on the goods he possesses.
