An animal showing signs of any disease at the time of ante-mortem inspection that would cause its carcass to be ultimately rejected on post-mortem shall be marked as:

Correct option is D

During ante-mortem inspection, food safety authorities examine live animals before slaughter to identify any diseases or conditions that could render the carcass unfit for human consumption.
If an animal is showing clear signs of a serious disease (such as tuberculosis, septicemia, or advanced parasitic infestations), it is marked as “Condemned”.
Such animals are not allowed to enter the food chain, and their carcasses are destroyed.
Other categories:
Inspected: Mark given to healthy animals that pass ante-mortem.
Suspect: Applied when animals show doubtful or mild abnormalities → these are kept under observation and subjected to detailed post-mortem inspection.
Diseased: Not an official marking term in ante/post-mortem classification systems; instead, “condemned” is used.
Thus, the correct answer is Option (d) Condemned.
