There are many benefits to timing your practice, including:
Statements (1) and (2) combined are sufficient. S1 and S2 gives that \(\angle ABC\) is the largest angle. Thus, the other two angles are smaller than 80 degrees and the answer to the question is "yes".

Answer: C
It would be really helpful if it is explained how many possible scenarios possible for which Statement 2 alone is insufficient.
Hi Bunnel , As per statement 2 angle ABC = 80 so it is clear that NOT ALL angles of triangle ABC is <90 as other to angles can be (0,100). Therefore statement 2 is sufficient . Am I right ?

Since the answer is C and not B, then obviously you are not right: {80, 80, 20} ALL the angles are less than 90 degrees {80, 95, 5} NOT ALL the angles are less than 90 degrees
_________________
From option 1 ac is the largest side that implies angle ABC to be the largest angle which equals 80 hence any other angle will be less than 80 degrees. Which implies all the angles of triangle ABCABC smaller than 90 degrees.
