If mary makes homemade jams that she sells to her local grocer, she is practicing:

select one:

a. b2b

b. b2c

c. c2b

d. c2c

c) C2B (Consumer to business)

Explanation: Consumer to business (C2B) is the business technique in which the consumer or customer generates the good or service and then businesses are offered to take that product or service. The case mentioned in the question is also similar where May sells the jams made by her to the local grocer who has his business.

Other options are incorrect because Business to business (B2B) is where two business party trade with each other, Business to consumer (B2C) is business offer the product or service to consumer and Costumer to costumer(C2C) is the private trading of service between two individual parties. Thus,the correct option is option(c).

i'm so sorry that's not a question and this isn't an answer
