Just look at the two first segments and it will give you the answer:

First segment : 1/4

Second segment : 1/3-1/4 = 1/12

Only (D) has both of those lengths

let the length of pipe is 12 units.

markings are at....0,3,4,6,8,9,12

length of segaments
1 (between 3-4 or 8-9)
2 (between 6-8)
3 (between 0-3 or 9-12)

on a 1 yard pipe = 1/12, 2/12 and 3/12 = 1/12, 1/6 and 1/4
Option D

Why dont we consider lengths between 8 and 12 of 4 units?

@siddhans, read the explanation in the OG. The diagram given there elucidates this problem very well, and you'll get the answer to your question in that explanation.

The way I imagined it was pretend we're taking numbers out of 100.

Quarter Cuts at 100 give you 25, 50, 75
Third Cuts at 100 give you ~33, ~67

This means that you have 1-25 or 1/4
You have 25-33 which is 8/100 ->2/25 ~1/12
33-50 gives you 17/100 -> 4.25/25 ~1/6

Only one with 1/4, 1/6, 1/12 is D

the first two fraction I understand is like this:

first be cut 1/4 and then be cut 1/3, so it 1/12, and why 1/6?
what do mean by this 33-50 gives you 17/100 -> 4.25/25 ~1/6?

well because the distance between 1 and 25 is 25, which means 25/100 which means 1/4
Distance between 25 and 33 is 8, 8/100 is roughly 1/12
and distance between 33 and 50 is 17, 17/100 is roughly 1/6

It can sound complicated but if you just think of it as a breakdown of 100, it might make more sense to you

(B) 1/4 and 1/3 only
(C) 1/6, 1/4, and 1/3
(D) 1/12, 1/6 and 1/4
(E) 1/12, 1/6, and 1/3

Since we want to find the fractions, we can assume some other length of the pipe which will make calculation easier. Take the length of the pipe to be 12-meter long (the least common multiple of 3 and 4.

In this case the branch would be cut at 3, 4, 6, 8, and 9 meters (in black are given fourths of the length and in red thirds of the length).

Distinct lengths would be: 3=3/12=1/4, 4-3=1=1/12 and 6-4=2=2/12=1/6 meters long pieces.
