For nuclei with A > 100,

For A=50 to A=80, the binding energy per nucleon increases on an average. For A>80, the binding energy per nucleon decreases on an average. Therefore, Option B is correct. For heavy nuclei with A>100, the unstable nucleus can break into two roughly equal parts with release of energy to attain stability. Therefore, option C is correct. For heavy nuclei with A>100, it is impossible to combine two nuclei to form a bigger nucleus. Lighter nuclei with A<100 can be combined to form a bigger nucleus with release of energy. Therefore, option D is not correct for A>100.
