Dear aspirant hope you are doing well..

manushy kee garbh avadhi 266 din aur 16 dinon ka maanak vichalan hai. ise mote taur par 270 dinon ka maana ja sakata hai. isalie sahee uttar 270 din hai

The gestation period of a human is 266 days and a standard deviation of 16 days. This can be roughly assumed to be 270 days. Hence the correct answer is "270 days".

Hope it's helpful for you..

Thank you
