Based on the premise "Ha! said the old gentleman, surveying him apoplectically.", can we conclude the hypothesis "The old man never saw him." is true (see options)?

Options: +yes. +it is not possible to tell. +no.
user
+no.

In the premise, the old gentleman is looking at "him" and even reacts by saying "Ha!", which means the old man must have seen him. The other options are wrong because:

+yes: It's not true since the old man has seen him.
+it is not possible to tell: We can tell from the premise that the old gentleman has indeed seen him.
