Since all the three fractions are <0 thus all three have to be multiplied with each other resulting in a fraction <1(III being <1).

Also point to note here that options available here (A,B,C,D) are not workable at all.

Let me know it this is helpful.

I. -18/19 > -1
II. -23/22 <-1
III. -17/16 <-1

IMO B & C

$$I*II = \frac{-18}{19}*\frac{-23}{22} =$$ +ve number >-1

$$I*II*III = -\frac{18}{19} * -\frac{23}{22} * \frac{-17}{16}= \frac{-18*23*17}{19*22*16}=\frac{-3519}{3344} <-1$$

IMO E

I don't quite understand the question. Like I multiplied by I or I by II and by III or what are we talking about? Sorry it might be dumb but I don't understand

The question language is very odd.

Options should be like
1 & 2
2 & 3
1 & 3

I dont understand what option
1 only
2 only
3 only would mean
