splitting interfaces between classes

I create a component where I need to implement 3 interfaces:

Interface A:

virtual void SetSomeInfo(Info) = 0;

Interface B:

virtual void SomeInfoChanged(Info) = 0;

Interface C:

virtual SomeData GetSomeDataX() = 0;
virtual SomeData GetSomeDataY() = 0;
virtual SomeData GetSomeDataZ() = 0;

Clients A and B use interfaces A and B to send some informations. Based on those informations a component builds some data structure. Client C using interface C gets data. I have two options:

1. Implements those interfaces in a single class.

2. Seperate interfaces between classes:

   class X: public A, public B 
   {
   public:
       //impl
       const Data& getData();
   
   private:
       Data data;
   };
   
   class Y: public C
   {
   public:
       //impl use getData 
   
   private:
       X x;
   };
   
   

Which design is better ? Do you have some other ideas ?
