First find how many groups of 4 pages Carla can read: 20 pages / 4 pages/group = <<20/4=5>>5 groups
Then multiply that number by the time per group to find how long it takes her to read those groups: 5 groups * 10 minutes/group = <<5*10=50>>50 minutes
Then add the time she spends answering questions to find the total time: 50 minutes + 14 questions * 1 minute/question = 50 minutes + <<14*1=14>>14 minutes = <<50+14=64>>64 minutes, which rounds up to 65 minutes. Answer: \boxed{B}.
