B Correct answer
Explanation

 The coordinating conjunction 'along with' necessitates that the verb connect with the first subject. 'High protein content' is a singular subject so all the verbs in the sentence should also be singular. 'Enables' is correct but the error is in the latter part of the sentence where 'make' is used instead of 'makes'. (B) rectifies the error.
