A deductive argument is one that the arguer wants to be deductively valid, that really is, to provide a guarantee that the conclusion is correct if the premises are correct.
This principle may alternatively be put as follows: in a deductive argument, the premises are designed to give such strong evidence for the conclusion that, if the premises are true, the conclusion cannot be wrong. A valid (deductively) argument is one in which the premises successfully ensure the conclusion. If a valid argument has true premises, it is also said to be sound. All arguments are either valid or invalid, and either sound or unsound; there is no such thing as being partially valid.
Therefore, the answer is deductive argument.
