Select all that apply. Which of these app titles follow recommended best practices?

Options A, C, and E are correct because they are concise, descriptive, and avoid promotional language. Best practices for app titles include keeping them short (under 30 characters), using relevant keywords, and focusing on the app's core function without being overly promotional. "Recipe hero" and "Recipe rescue!" are short and clearly indicate the app's purpose. "Recipes to the rescue!" is also concise and descriptive. Options B and D are incorrect. Option B, "Recipe rescue: download today!", includes a call to action ("download today!"), which is considered promotional and generally discouraged in app titles. Option D, "Recipe HERO!", uses all caps and an exclamation mark, which can appear spammy or aggressive and doesn't align with best practices for a professional and user-friendly title.
