How would one characterize the solution in a flask, at the equivalence point, for an experiment where 60.0mL of 0.40 M trimethylamine, (CH _{3})_{3}N (in the flask), is titrated with 0.30 M HNO_{3 }(in the buret)?

(a) the solution is now a weak base

(b) the solution is now a weak acid

(c) the solution is now a strong base

(d) the solution is now a strong acid

(e) it is now a neutral solution

(f) it is now a buffer solution
