This is a pure recall question about the wording of the Preamble, and the only safe way to answer it is to run the actual sentence through your head rather than rely on the familiar French slogan.
The Preamble promises to secure to all citizens JUSTICE, social, economic and political; LIBERTY of thought, expression, belief, faith and worship; EQUALITY of status and of opportunity; and to promote among them all FRATERNITY assuring the dignity of the individual and the unity and integrity of the Nation.
Read that off and the running order is Justice, then Liberty, then Equality, then Fraternity, and finally the unity and integrity of the Nation, which sits inside the fraternity clause right after the dignity of the individual. A short memory tag is JLEF, and the trap it protects against is the slogan of the French Revolution, Liberty Equality Fraternity, which has no Justice at the front. India's framers put Justice first, and the arrangement carries meaning: justice comes first, liberty is enjoyed within it, equality gives liberty real content, and fraternity holds the whole thing together.
Now attach the numerals given in the question. Justice is III. Liberty is II. Equality is I. Fraternity with dignity of the individual is IV. Unity and integrity of the Nation is V. That produces III-II-I-IV-V.
Let's summarize:
So option (B) is the answer.
