‘Assume’ is English; the correct Portuguese verb is ‘assumir’.
Quem assume isso?
Learners sometimes drop the auxiliary ‘vai’ and say ‘Quem assume isso?’, which sounds unnatural for a near‑future question.
Quem vai assumir a tarefa? (incorrectly using ‘isso’ after a feminine noun).
If the object is feminine, you must use ‘aquela’ or ‘ela’; using ‘isso’ for a feminine noun is a mismatch.
