Answer:
d. The pH of the beaker`s contents will decrease.
Explanation:
Since the new substance is an acid and has a very low pH, that is 1. it will reduce a little bit the pH of the original base (NaOH). Some ions of hydrogen of the acid are going to react with the hydroxyl group of the sodium hydroxide to form water.
Since the differences of the volume is big, only a small part of the base is going to be neutralize, but at the end, the final pH of the solution is still going to be a base.
Hope this information is useful.
