Is there any good design pattern or solution to handle the transition behavior having a dependency between states?

Suppose there are four states like below.

A state
B state
C state
D state

And there is a complex transition dependency like below.

A is default state
B is C,D state's precondition
C is D state's precondition

Currently, my idea is the following.

if(conditionXXX){
 state = B;
}
else if(B && conditionYYY) {
 state = C;
}
else if(C && conditionZZZ) {
 state = D;
}
else {
 state = A;
}

But I'm considering that is not a nice solution. Is there any good design pattern or a good solution?
