The correct answer is A.
The word “sorry” can be used to express sympathy or regret. In this case, Edie is expressing sympathy for the old lady. The preposition “for” is used to express sympathy or concern for someone.
The other options are incorrect because they do not express sympathy or concern. The preposition “off” is used to express a state of being detached or removed from something. The preposition “of” is used to express possession or ownership. The preposition “from” is used to express a state of being away from something.
Here are some examples of how the word “sorry” can be used to express sympathy or regret:
- I’m sorry to hear that you’re sick.
- I’m sorry I spilled your drink.
- I’m sorry I didn’t call you back sooner.
