Answer:
The correct answer to the following question will be Option D (Material Incentive).
Step-by-step explanation:
A conditional motivator is an Incentive. Material Incentives are economic advantages or incentives, such as travel plan, insurance packages or discount.
If Shelly decided to join the Comato Group, an interest group advocating organic food consumption and speaks out on the use of chemicals in agriculture. Shelly believes that the group's advantages to its participants are what inspired her to join the party. Member advantages include a steady supply of organic agriculture supplies and discounts on organic products. So, she must be entering an invitation to the material.
Therefore, Material Incentive is the right answer.
