The ozone layer in the stratosphere absorbs most of the sun's harmful UV-B radiation. Depletion of this layer means less absorption, leading directly to higher levels of UV-B radiation reaching the ground. The other options (decrease in yield of plants, skin cancer, change in climate) are consequences or indirect effects resulting from increased UV radiation or other related atmospheric changes, not the direct physical effect of ozone depletion itself on radiation levels.
The direct effect of Ozone depletion would lead to:
