The correct answer is option 4, Venus. Venus is known as the Morning Star because it is often the first bright object visible in the morning sky before sunrise. Venus is the second planet from the Sun and is one of the brightest objects in the night sky. Due to its proximity to the Sun, Venus can only be seen either shortly after sunset or shortly before sunrise. When it is visible in the morning, it appears as a bright, star-like object that is often mistaken for a star, hence the name "Morning Star". This phenomenon occurs because Venus is closer to the Sun than the Earth, causing it to appear on the eastern horizon before the Sun rises in the morning.
