Yes, you are correct. The noun "Congress" is properly capitalized. Capitalization is important in English language, especially when it comes to the first letter of nouns. Proper nouns, like names of specific places, people, organizations, and titles, are typically capitalized. In this case, "Congress" refers to a specific institution and is therefore capitalized. On the other hand, "telephone" (option A) and "frame" (option B) are common nouns that are not specifically capitalized unless they begin a sentence. "orlando" (option C) is a common noun as well, but it should be capitalized as "Orlando" because it is a proper noun referring to a specific city.
