Question

Food poisoning bacteria will multiply readily between

• A. -18${}^o$C- 0${}^o$C
• B. 0${}^o$C- 5${}^o$C
• C. 5${}^o$C- 63${}^o$C
• D. 63${}^o$C- 90${}^o$C

Answer 1

The correct option is C 5${}^o$C- 63${}^o$C

even though the food poisoning bacteria grow at the temperature of 37 degree centigrade they start multiplying readily at approximate temperature between 5 to 63 degree centigrade.

So, the correct answer is '5${}^0$ - 63${}^0$
