Answer:
The correct answer is letter "A": to appeal to both high and low involvement consumers.
Explanation:
Strong arguments are those that provide probable support for an idea. Weak arguments fail to provide support for different matters. Then, when talking about marketing, strong arguments are more likely to engage consumers with a product while weak arguments can attract consumers at low levels but the ideas lack reliability.
Thus, infomercials can make use of both strong and weak arguments at different levels of consumer involvement.
