Answer:
The correct answer is:
- Él tiene una cicatriz en su pierna
Step-by-step explanation:
The substantives showed like options to answer are "corte, dolor and cicatriz" which translate in English cut, pain, and scar, each one of these have a possible undetermined article, which could be:
- Un corte.
- Un dolor.
- Una cicatriz.
How the one substantive that can use the article "una" (the same that is in the sentence) is cicatriz, this is the reason for selecting it.
