Help with wife getting state pension and benefits

Hello everyone, I'm new to this group, just wanting advice from anyone in my situation regarding my wife who turns 66 on the 8th December, she claims PIP,and EESA ,and I claim Carer's allowance. She has had a letter off the DWP asking her how she wants to have her State Pension paid, does anyone know if she has to inform them on her benefits ie will she still get them?it's a minefield for us ,anyone any ideas?oh and by the way I turn 66 on 27th April 2025 ,will my Carer's allowance stop?Any advice greatly appreciated.
