Answer:
B.How to make a friend
Step-by-step explanation:
An abstract process is one in which there is no definite form of action. For example, making a friendship has no definite recipe, because friendships depend on tastes, affinities, empathy, and other characteristics of the human perspective of socialization. Instead, baking a cake, lighting a fire, or planting flowers are tasks whose execution has a predefined set of steps. For example, to make a cake you use a ready recipe. For planting flowers and lighting fire there are specific techniques defined so that this can be done in the best way.
