Which of these hypothetical scenarios are examples of pleiotropy? select all that apply?

I found the options to the exercise on the internet. Here are they:
"A. A defect in a single gene causes a disease in which affected individuals have longer limbs.
B. A defect in a single gene causes a disease in which affected individuals have longer limbs and vision problems.
C. A single gene determines whether or not an individual is colour blind.
D. A single gene determines the hair and eye colour of an individual.
E. Multiple genes determine the height of an individual."

The scenario B is the one that best describes a pleiotropy. Pleiotropy is the phenomenon that is present when a single gene influences the phenotype of two or more different traits that have no direct relation. A and C scenarios are one gene-one characteristic. E scenario is multiple genes-multiple characteristics. D scenario although it shows a gene being related with two different "organs", both traits are easy to relate as the base of it is coloured pigmentation in cells.

The best way to tell its true color is to look at the minerals streak
