Hello!
So lets talk about what AU means. AU mean astronomical units and means the distance from the distance from the earth to the sun.
I believe Planet A is Venus. This is because, the distance of planet Venus to the sun is 0.72 AU.
I hope it helps!
By the first distance, I'd say Venus (0.72 AU)
By the second distance, I'd say it's Saturn (9.54 AU)
But you also say it has no visible rings so the answer is VENUS.
Hope it helped,
Happy homework/ study/ exam!
