Since the number sets follow this pattern of inclusions:
[tex] \mathbb{N} \subset \mathbb{Z} \subset \mathbb{Q} \subset \mathbb{R} \subset \mathbb{C} [/tex]
and [tex] -1 \in \mathbb{Z} [/tex], we can deduce that -1 is also a real number and a complex number (since if an element belongs to a set, it also belongs to all the supersets of its set).
So, the correct options are B and D.
