Answer:
C.
Step-by-step explanation:
In some societies or cultures, the birth of sons is favored over that of daughters. This favor causes demographic imbalance and results in skewed sex ratios.
The two factors that can make it difficult to address skewed sex ratios are limited medical technology combined with coercive population control policies. This is so because limited medical technology will limit the modern reproductive technology that helps in prenatal diagnosis of child and orevent sex-selective abortions. Limited medical technology along with coercive population control policies helps to create a strong population control policy that culture or society have to follow irrespective of discrimination against female births.
Combination of limited medical technology combined with coercive population control policies will result in balance sex ratio.
Hence, the correct answer is "C".
