Select the correct answer. What is the climax of the passage?

Mason was walking through the mall, wondering what he should buy for his mother. Today was her birthday. Mason had struggled all week trying to find the perfect gift, but nothing seemed right. He first thought about getting her a dress, only to realize that he had no idea what size she wore. Then he thought he’d get her a book, since his mother loved to read. But the book shop was large, and Mason couldn’t be sure which books she had already read.

He thought to himself, “I don't know what Mom likes. I want to get her something that will make her happy.”

That’s when he saw Little Potter’s Florist and Gardening Shop. His mother loved gardening! Mason ran over to the store. The owner of the store, Angela, was surprised to see Mason. Mason told her he was there to get a gift for his mother. Angela wrapped up five packets of seeds, five planters, and a new weeding fork. She also put together a fresh bouquet of roses for Mason to give to his mother.

When the time came to present his gift to his mother, Mason grew anxious. He didn’t know whether or not she would like the gardening supplies. He wondered if he should have bought a dress like he had initially planned. Of course, it was too late to make a change, so he went to the kitchen where his mom was busy preparing a chicken dinner.

Mason sneaked behind her and placed the gift on the table. He held out the bouquet and shouted, "Happy Birthday, Mama!"

His mother was startled, but she accepted the bouquet with a smile. As she began to open the package, Mason could feel nervousness creeping up on him again. His mom remained silent as she removed the contents of the package. She then turned and hugged Mason with tears in her eyes. Mason knew his mother loved the gifts. She always cried when she was really happy.
