Looking at the sentence given we find that.

• The verb here should be singular as the subject is singular.
• It is 'challenge' thus the subject must agree with the verb.
• The verb in the sentence is preceded by the word now hence Option 1 were cannot be used. 
• Option 2 is wrong because will can only be used with Future tense.
• Thus Option 3 is the correct answer as Is is a singular verb.

Hence the correct option is Optio 3 i.e Is to work out. 

Thus the correct sentence will be: 'The Finance Minister has acknowledged that the challenge before the government now is to work out both policy and investment measures to boost momentum.'
