Which of the following is not the priority rule for R, S Configuration?

#Unit 1. Molecules and their Interaction Relevant to Biology

If the four atoms attached to the chiral center are all different, priority depends on atomic number, with the atom of lower atomic number getting lower priority.
If the two atoms attached to chiral centers are same, the atoms attached to each of these first atoms are compared
When there is a double bond or triple bond, both atoms are considered to be duplicated or triplicated
If the four atoms attached to the chiral center are all different, priority depends on atomic number, with the atom of higher atomic number getting lower priority.

#Unit 5. Developmental Biology

A researcher performed an experiment during vulva formation in C.elegans;

I- In first experiment destroyed anchor cell

II- In second experiment destroyed three central VPCs

What kind of conclusion has been drawn by these experiments?

a) I-Three cells out of six of the equivalence group divide once and contribute to the vulva formation

b) I-all six cells of the equivalence group divide once and contribute to the hypodermal tissue

c) II-three outer cells, which normally form hypodermis, generate vulval cells instead

d) II-three remaining cells normally formed hypodermis as usually
