This question can be easily answered just looking at a periodic table for reference.
No reason why you shouldn't be able to do it yourself. If you need a good online one check out ptable.org.

Anyways...
Series 1 is the correct answer. Beryllium is an (alkaline earth) metal, silicon is a metalloid, chlorine is a (halogen) nonmetal, and krypton is a noble gas.

(Series 2...carbon is a nonmetal, nitrogen is a nonmetal, neon is a noble gas, and argon is a noble gas...there is no metal or metalloid.
Series 3...potassium is an (alkali) metal, iron is also a metal, boron is a metalloid, and fluorine is a (halogen) nonmetal. There is no noble gas.
Series 4...sodium is an (alkali) metal, zinc is a metal, arsenic is a metalloid, and antimony is a metalloid...there is no noble gas.)
