Explanation / Answer

4)

Oxidation number of H = +1

Oxidation number of O = -2

lets the oxidation number of Te be x

we have below equation to be used:

1* oxidation number (H) + 4* oxidation number (O) + 1* oxidation number (Te) = net charge

1*(+1)+4*(-2)+1* x = -1

-7 + 1 * x = -1

x = 6

So oxidation number of Te = +6

Answer: c
