Conditional Sentences
Conditional sentences are characterized as sentences that involve either a condition or a hypothetical situation and a likely consequence associated with it.
As per the rule, in case the 'if clause' or the 'conditional clause' is written in present indefinite tense(subject + V1 + s/es), the consequential clause would be framed in 'future tense.'
Therefore, the correct options to fill the given sentence would be 'keep' in the 'if clause' and 'will be' in the consequential clause.
Thus, option c is the correct answer.
