Which statement is incorrect in respect of a "sonogram"?

It is an x-ray like diagnostic device based on ultra-violet technology

The correct answer is Option 1: It is an x-ray like diagnostic device based on ultra-violet technology

A sonogram is a diagnostic device based on ultra-sound technology, not ultra-violet technology. It was originally developed for legitimate medical purposes, such as detecting genetic or developmental abnormalities in the foetus. However, it has also been misused for prenatal sex determination and sex-selective abortions. Therefore, Option 1 is the incorrect statement.

NCERT: "Several factors may be held responsible for the decline in the child sex ratio, including severe neglect of girl babies in infancy, leading to higher death rates; sex-specific abortions that prevent girl babies from being born; and female infanticide (or the killing of girl babies due to religious or cultural beliefs). Each of these reasons point to a serious social problem, and there is some evidence that all of these have been at work in India. Practices of female infanticide have been known to exist in many regions, while increasing importance is being attached to modern medical techniques by which the sex of the baby can be determined in the very early stages of pregnancy. The availability of the sonogram (an x-ray like diagnostic device based on ultra-sound technology), originally developed to identify genetic or other disorders in the foetus, are misused to identify and selectively abort female foetuses.
