For statement 2 following cases are possible:
A--(5)--C-------(20)-----------B
C--(5)--A-------(15)---------B
So this statement is not sufficient.
Answer: A.

|----|------------------|
A C B
|- 5--|
|--------20-------|
|-----------25----------|
Only way statement 1 works is above. Statement 1 is sufficient.
Statement 2 is a trap. If you do statement 1 first, you may be fooled into thinking, because A is to the left of point B that it is the same as above. However, it could also be:
|----|------------|
C A B
|-5--|
|---20-------|
|-------20--------|
A C B
|- 5--|
|--------20-------|
|-----------25----------|
Only way statement 1 works is above. Statement 1 is sufficient.

Nice question.. Thanks for the answer Bunuel...
I tht it was D till i read your explanation of why statement 2 is not sufficient..
I hadnt considered the possibility with C all the way to the left..

AC= 5, BC = 20
Stmt 1: AB = 25; From the properties of number line, C must be between A and B (does not matter on which side in the line). Sufficient
Stmt 2: A lies to the left of B; C could be between A and B or it could be left to A making AC=5, AB = 15 and BC = 20. Insufficient.
Answer A.

Good c-trap question.
there are 4 ways this number line can be drawn
A-------5-------C-------------20--------------B
B----------------15----------------A-------5-------C
B---------------------20-----------------------C-----5-----A
C-----5-----A------------------15------------------B
from (1) only the 3rd line fulfils the criteria of AB = 25 and C is in between A and B. SUFFICIENT
(2) A is to the left of B in lines 1 and 4, we can't decide if C is in between A and B. INSUFFICIENT
hence A is the answer
A-------5-------C-------------20--------------B
B----------------15----------------A-------5-------C
B---------------------20-----------------------C-----5-----A
C-----5-----A------------------15------------------B
