Hey there! I did part A for this question since the other part would just be the exact same process. You basically have to set up an ICE chart first to get expressions for your equilibrium concentrations. From there you can solve the concentration of H3O+ and get the pH. For Parts B and C you just have to replace the part of the Ka expression with the appropriate initial concentration and the process should just be the same. I hope this helps!
