Thomas performed an experiment to measure the temperature of water as he heated it on a hotplate. At the end of his experiment, he plotted the results as shown in the graph below. Pls I need this

I thought A not C

Explanation:

But ill double check

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
