(D) The initial total height of $35$ girls is calculated as: $35 	imes 160 = 5600 \,cm$.To find the actual total height,subtract the incorrect value and add the correct value: $5600 - 144 + 104 = 5560 \,cm$.Now,calculate the actual average height by dividing the actual total height by the number of girls: $\frac{5560}{35} \approx 158.8571... \,cm$.Rounding off to two decimal places,we get $158.86 \,cm$. (Note: Based on the provided options,the closest value is $158.85$ or $158.86$. Re-calculating $5560/35 = 158.857$,which rounds to $158.86$. Given the options,$158.86$ is the mathematically correct rounded value,but $158.85$ is provided as option $D$).
