Answer 2

An isotone of Ge is (d) As.

Explanation:

Isotones are elements which have the "same number" of neutrons. These elements might have differing molecular weights due to the difference in the "number of protons"; therefore, a difference in their atomic number.

Germanium has only one other element which shows the same number of neutrons which is Arsenic.

Both Germanium and arsenic have 44 neutrons. Contrary to this, isotopes are elements which have the "same number" of protons but "different number" of neutrons.
