Answer:
Rukmani's struggle to feed her family during the drought is an example of an external conflict.
Step-by-step explanation:
External conflicts are those that can be caused by another character, by the environment in which the character lives, or by some situation that the character is living. In the case of the excerpt shown in the question, there is a situation where there is a drought in the environment where Rukmani lives, so he is struggling to feed his family. As Rukmani's fight is caused by the drought in the place he lives, we can conclude that Rukmani is facing an external conflict.
