Concept:The term "sex ratio" can be expressed differently in various regions — either as males per 100 females or as females per 1000 males. In Asia, the sex ratio (females per 1000 males) is generally low, not high.
Explanation:Option A: In some countries, sex ratio is expressed as the number of males per 1000 females. This is a valid way to report the ratio. So, A is correct.
Option B: In India, sex ratio is officially expressed as the number of females per 1000 males. This statement is correct.
Option C: At the world level, the sex ratio is approximately
102 males per
100 females. This is accurate and widely accepted. So, C is correct.
Option D: In Asia, the common measure is females per 1000 males. Due to cultural preferences for male children, many Asian countries (e.g., China, India) have fewer females per 1000 males. That means the sex ratio is low—not high. Therefore, the statement "In Asia, there is high sex ratio" is incorrect when referring to the standard measure used in the region.
Answer:Option D
