Statement I: "The company plans to launch their new product in the upcoming week." The correct form should be "The company plans to launch its new product in the upcoming week." Since "company" is a singular entity, the pronoun "its" should be used instead of "their." Statement II: "The professor provided the students with a comprehensive study guide for the final exam." This statement is grammatically correct. Statement III: "My parents always encouraged me to pursue my dreams, and I'm grateful for their support." This statement is grammatically correct.
