As the passage refers to an action in the future, the passage will take the base form of the verb with the auxiliary verb 'will' to indicate the future. 
"Inaugurated" in option A is the base form of the verb, but without the future denoting auxiliary 'will'. Thus, this is incorrect.
"Will inaugurate" in option B is correct as it takes the auxiliary verb 'will' which denotes the future tense alongside the base form of the verb. This option shows the future tense. Thus, this is correct.
"Has inaugurated" in option C is incorrect as it refers to an action completed in the past.
"To inaugurate" is the to infinitive which is incorrect as it is used to express someone's opinion about something etc. 
Therefore, option B is correct.
