Question

Which line of dialogue would be appropriate for a formal character, such as a prosperous businessperson?

“I am very glad to meet you again, Ms. Li.”
“Hi, Ms. Li. It’s great to see you again.”
“It is my great pleasure to see you again, Ms. Li.”

Answer 1

"The correct answer is It is my great pleasure to see you again, Mas. Li."

Step-by-step explanation:

Once you meet someone for the first time, you cannot "meet them again"

the use of the word 'Hi" is informal

Answer 2

As you are talking about a prosperous businessperson then the best option in here is to say: I am very glad to meet you again, Ms. Li. This is something very polite but not improper. It is just the right fit
