Noriko's Grandmother Has Become Hard-Of-Hearing

Noriko's grandmother has become hard-of-hearing. Lately, she no longer wants to participate in the family's social occasions because it embarrasses her when she can't hear what anyone is saying. She has even told her granddaughters to leave her alone. Noriko, who is very close to her grandmother, asked her friends what she should do. The best advice she received was

A) "Tell her she should try harder to pay attention."
B) "Talk to her in a quiet place and use a voice that is a little louder than usual."
C) "Use a high-pitched voice and don't look directly at her when you speak."
D) "Use a very loud voice, even shout if necessary."
