B
positive
C
negative
D
zero, positive or negative
Solution
Verified by Toppr

#### We know that mass defect = combined mass of nucleons − mass of the nucleus.Since mass defect is always positive quantity so the difference of nucleus and the combined mass of its nucleons will be negative. The combined mass is greater than the mass of nucleus.
