The answer is (a). Autosomal dominant disorders can be expressed in a heterozygous state thats why it is called dominant. It is the autosomal recessive state which is always expressed in homozygotes.
Its technically not the right answer {A} because option is
"it always affects homozygotes" and thats true it always affects homozygotes, and it "can" affect heterozygotes as well coz its a dominant condition, option A would have been right answer if it was quoted as "only affects homozygotes". (that is untrue and that is what asked in the question "all are true except")
