A. -146.56
B. -45.52
C. 45.52
D. 140.20

Step 1 ：The problem is asking for the weight of the Blue Hope diamond. We know that the Blue Hope diamond weighs 33.68 carats less than the Idol's Eye diamond, which weighs 79.2 carats.

Step 2 ：So, to find the weight of the Blue Hope diamond, we need to subtract 33.68 from 79.2.

Step 3 ：\(idols\_eye\_weight = 79.2\)

Step 4 ：\(blue\_hope\_weight = idols\_eye\_weight - 33.68\)

Step 5 ：Substituting the given value, we get \(blue\_hope\_weight = 79.2 - 33.68\)

Step 6 ：Calculating the above expression, we get \(blue\_hope\_weight = 45.52\)

Step 7 ：Final Answer: The weight of the Blue Hope diamond is \(\boxed{45.52}\) carats.
