A logically inconsistent statement.

Since you didn't include the statements in your question there is no way for us to know
The answer cannot be "a proof" since that can equally be used to show that a statement must be false.
Logically invalid statements.
A proof is a very abstract thing. You can write a formal proof or an informal proof. An example of a formal proof is a paragraph proof. In a paragraph proof you use a lot of deductive reasoning. So in a paragraph you would explain why something can be done using postulates, theorems, definitions and properties. An example of an informal proof is a two-column proof. In a two-column proof you have two columns. One is labeled Statements and the other is labeled Reasons. On the statements side you write the steps you would use to prove or solve the problem and on the "reasons" side you explain your statement with a theorem, definition, postulate or property. Proofs are very difficult. You may want to consult a math teacher for help.
Steps in a geometric proof do not require support

Conjecture and Guess.
which of the following types of statement can be used to explain the steps of proof?

conclusion
no each statement should have a reason/explanation for it to be true
Yes- provided its proof does not depend on the result you are using it to prove.
