Hi 奇迹 I suggest that none of these words will fit, because the sentence does not make sense in English with any of them. You could say: 'He is such a great scientist; many people look up to him', 'or 'He is a great scientist who many young people look up to', but whichever way you look at it, (b) is definitely not the right answer.

You should chose only C. Who. You are talking about a scientist who is a person, so you always have to use 'who' in this situation. Many people also use 'that' in spoken English, but this is not correct English. You can not use B. This is completely wrong. I hope this helps you. Ru guo ni you bie de wen ti wo ke yi bang zhu ni. Wo hui shuo yi dianr Pu Tong Hua. If you like, add me as your friend. Zai jian....
