Answer:
d. Tryptophan would bind to the repressor
Explanation:
However,the repressor would not be able to bind to the operator and switch off transcription.The cell would still be making tryptophan even though it is being supplied by the medium in which it is growing.This is a waste of energy.
If the mutation occurs during meiosis, the mutation will be incorporated into a gamete. If that gamete is the one that eventually fuses with another gamete (i.e. if it's the sperm that fertilizes the egg), that mutation will be passed on to the offspring. As all the offspring's cells are the result of the first two gametes, all the organism's cells will have that mutation. Obviously this can have dire consequences for the offspring, if the mutation is harmful.
