A. The wavelength of light that is emitted is 122 nm.
<h3>
What is wavelength?</h3>
Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.
<h3>Wavelength of light is emitted</h3>
When an electron falls from the n = 2 to the n = 1 energy levels in a Hydrogen atom, the wavelength of light is emitted is calculated as follows;
¹/λ = R(1/n₁² - 1/n₂²)
¹/λ = 109677(1/1 - 1/2²)
¹/λ = 109677(1 - ¹/₄)
¹/λ = 82,257.25
λ = 1/8,225.25
λ = 1.22 x 10⁻⁵ cm
λ = 1.22 x 10⁻⁷ m
λ = 122 nm
Thus, the wavelength of light that is emitted is 122 nm.

Explanation:
Sulfur has valence electron 6 and oxygen has 6*3 = 18 valence electrons. In this drawing, you'll see that sulfur violates the octet rule that is it has more than 8 electrons but it is legal since sulfur is in 3rd period, and elements that fall in 3rd period or more in periodic table can use their d orbitals and others to go beyond the normal "8" electrons in valence shell rule which is octet rule
All the formal charges are minimized...that is everything has formal charge of 0 in this structure which is always encouraged.
