Answer 1

From the table,

Total number of people=$108+44+206+85+57$

$=500$

since 1) is correct

From the table type D ASD is 85 since (4) is correct.

Relative frequency of people living with type C ASD is given by

$=\frac{205}{500}$

$=0.41$

therefore (3) is also correct.

But from the table frequency of people living with type B ASD is 44. Therefore (2) is incorrect.

The answer is (2)
