I agree with you. The 'trick' in these question is to ignore the pulley connected to the ceiling, this pulley simply changes the direction of the rope.
Count the number of strings holding up the weight, in E it is 3..... Therefore this needs the smallest tension in the string (1/3 the weight)

What do you think F = m a hass to do with this problem?
