Explanation:
Conditional sentences display factual implications, imaginary or hypothetical situations, and their consequences. These sentences consist of a conditional clause beginning with 'if' and the main clause.
In the first conditional form, the conditional clause is written in 'simple present tense'(Subject + V1) while the main clause is written in future simple(subject + will/shall + V1). The 'if' clause shows the condition or situation while the main clause shows the consequence. The given sentence as per this rule is filled as above.
