Correct option is B
Assumption 1: "The statement is an unrealistic assurance." This is not implicit because the statement does not explicitly suggest or indicate that the assurance is unrealistic. The statement could be genuine or exaggerated, but the assumption about it being unrealistic is not necessarily implied.
Assumption 2: "People want to invest their savings to increase their income." This assumption is implicit because the marketing executive is trying to appeal to the desire of people to grow their savings by offering an investment scheme, which suggests the belief that people are interested in increasing their income through investments.
The correct answer is (b) Only assumption 2 is implicit.
