The correct answer is: Only assumption I is implicit.
The statement “Banking services are fine tuned to meet growing business needs” implies that banking is a part of business activity. This is because the statement says that banking services are fine tuned to meet the needs of businesses. This means that businesses need banking services, and that banking is therefore a part of business activity.
The statement does not imply that industrialists prefer better banking services. This is because the statement does not say anything about what industrialists prefer. It only says that banking services are fine tuned to meet the needs of businesses. This means that businesses need banking services, but it does not say anything about what kind of banking services businesses prefer.
Therefore, only assumption I is implicit in the statement.
