Select the option that expresses the given sentence in indirect speech.

“How beautiful she is!” said Betty.

Betty exclaimed with joy that she was very beautiful.

The correct option is:

Betty exclaimed with joy that she was very beautiful.

The other options are incorrect because they do not follow these rules:

• Betty exclaimed with joy how beautiful she was. - This sentence does not change the present tense to the past tense.
• Betty exclaimed with joy she is very beautiful. - This sentence does not change the exclamatory sentence to a declarative sentence.
• Betty exclaimed with joy how beautiful she is. - This sentence is the same as the direct form of the sentence, and it does not add the word "very" to emphasize Betty's admiration.
