Few flaws in the question..

1) if they are walking to meet each other, they have to walk towards each other. However statement II is contradictory, saying they walk in same direction. Why would someone walk towards EAST to meet someone in WEST.
Question should just say, they both start walking in a straight road etc

2) if the Question is framed the way it is above, Ans will be E as Alfred with higher speed starts moving in opposite direction, Botham can never catch up...
Question should say that Alfred is moving towards Botham

If the question is this way..

Statement I would be sufficient...
Distance between them 200..
1) if both move towards each other, combined speed=30+10=40
Time to meet each other =200/40=5
2) if B is moving away from A, combined speed=30-10=20
Time to meet each other =200/20=10

In each case LESS than 12
Sufficient
