Final answer:
The two countries where sex-selective abortion is significantly practiced are India and China, influenced by cultural preferences for male children and policies like China's former one-child policy.
Step-by-step explanation:
The two countries in which sex-selective abortion appears to be practiced in significant ways are B) India and China. Sex-selective abortion is a practice where a pregnancy is terminated based upon the predicted sex of the infant. This practice has been linked to cultural preferences for male children, which has created a skewed gender ratio within certain populations. For instance, policy measures like the one-child policy in China led to an increase in the rate of sex-selective abortions due to a traditional preference for sons. Similarly, in India, there have been reports of sex-selective abortions, which has led to concerns about the future demographic makeup and the potential social implications of such practices.
