Answer:
Option C - The sympatric salamander populations evolved their present body sizes after they became sympatric.
Explanation:
First, note the definitions of each terms.
1) Sympatric occurs when organisms especially of same species occurring in the same, or in overlapping territory, do not interbreed.
2) Allopatric occurs when organisms are NOT living in the same territory and thus unable to crossbreed.
On 1st QUESTION
The argument would be strengthened by the failure of P. cinereus and P. hoffmani to crossbreed making traits for body size to become distinct (dissimilar) in each specie.
On 2nd QUESTION
Definitely, salamanders species occurring in the territory, do not interbreed after they became sympatric, thus, making characters among same species to be increasingly different over generations.
