Fill in the blanks with appropriate Articles. ________ sun rises in _…

The correct answer is Option (1) → The, the

"The" with unique objects and directions:

• Things of which there is only one take the definite article "the": the sun, the moon, the earth, the sky.
• The points of the compass take "the" after a preposition: in the east, to the north.

Complete sentence: The sun rises in the East.

Why the Other Options are Incorrect?

Option 2: A, a — Incorrect. "A" is used for one of many. There is only one sun and one east.

Option 3: The, a — Incorrect. The first blank is right, but a direction takes "the", and "a" cannot come before the vowel sound of "East".

Option 4: An, a — Incorrect. "An" cannot come before the consonant sound of "sun", and neither blank takes an indefinite article.
