I have to make a small circuit with an integrated FLIP FLOP that has this function:
1. pin A and B input to 1, pin C output goes to 1
2. when pin A is 1 and pin B is 0, pin C goes to 0 and remains there even if pin B returns to 1
3. pin C returns to 1 only when pin A goes from 1 to 0 and then to 1 again and with pin B to 1

If you have to use discrete components (transistors, diodes, resistors) you are on your own. Otherwise any flip flop chip listed as D,-type or JK flip flop should be essentially what you need. Cd74HC74 for example (has two independent flip-flop circuits on each chip. Check out the datasheet or Google how to use one.
Which search terms have you already tried? I am surprised if you cannot find a dozen great YouTube videos of how to use a D-Type Flip Flip Circuit. Please copy the HTML address of the search and post it here. I can help you search for a suitable video but I ain't going to do it without your initiative.
