1)
Does not give enough information. P could be one of an infinite amount of numbers 28, 168, 336...
INSUFFICIENT
2)
As with 1), this is not enough information. P could be 12, 24, 120... etc.
INSUFFICIENT
1+2)
While we know that P is divisible by both 14 and 12, we do not know if P is divisible by 14*12.
P could be a number which is divisible by 168, like 168. However, P may be a number which is not divisible by 168, like 84. We cannot pinpoint whether it is or isn't with the information is 1) and 2).

1. P is divisible by 14 - Clearly not sufficient
2. P is divisible by 12 - Clearly not sufficient
1 & 2 p has to be divisible by LCM of 12 and 14 i.e. 84. In this case, P can be 84, 168 .... therefore it may or may not be divisible by 168.
2. P is divisible by 12 - Clearly not sufficient
