Final answer:
The correct verb is 'hable'
Step-by-step explanation:
The correct verb to fill in the blank in the sentence is A. hable. 'No es cierto que Tomás' is a negative statement, so we need to use the subjunctive form of the verb. In this case, we use the present subjunctive form 'hable' to agree with the third person singular subject 'Tomás'.
