Whomever is responsible for watching the little children at the park and making sure they don't run out into the road?

what is the best way to write the underlined part of the sentence?
a.
which is responsible
b.
who is responsible
c.
whom is responsible
d.
leave as is

B)

Explanation:

The correct question should be ''Who is responsible for watching the little children...?'' because in that case 'Who' will be the most appropriate solution.

If we put Which or Whom it would be like the previous text of the question is missing and with Who this question is complete. If we leave it with Whoever is would be like the rest of question is missing.
