Is this right?

A spinning figure skater push his arms out as he rotates on the ice. As he push his arms out of body, what happens to his angular momentum \( L \) and kinetic energy K? L increases; \( \mathrm{K} \) stays the same. \( \mathrm{L} \) and \( \mathrm{K} \) both decrease. \( \mathrm{L} \) stays the same; \( \mathrm{K} \) increases. \( \mathrm{L} \) and \( \mathrm{K} \) both stay the same. \( \mathrm{L} \) stays the same; \( \mathrm{K} \) decreases.
