Concept:A manifesto is a formal public declaration of the policies and aims of a political party or candidate.
Explanation:The term "manifesto" describes a published document issued before an election.
In it, a political party or candidate clearly states what they intend to do if they come into power.
It outlines their planned policies, goals, and programmes for the public.
This document helps voters understand the party's direction before they cast their votes.
A manifesto also acts as a promise between the party and the voters.
After the election, the public can judge whether the party has kept its promises.
The other options do not fit this exact meaning.
A "guide to government" and "steps to govern" are not standard election terms.
A "policy paper" is broader and is not specifically an election declaration by a party.
So, the correct option is the one that directly names this public election declaration.
Answer:B. manifesto
