Select the grammatically correct and pure sentence structure from the choices given:
- Aमैं गाने की कसरत करता हूँ।
- Bमैं गाने का अभ्यास करता हूँ।
- Cमैं गाने का शौक कर रहा हूँ।
- Dमैं गाने का व्यायाम कर रहा हूँ।
Solution & Step-by-step Explanation
In Hindi linguistics, the repetitive training or preparation for fine arts like singing, playing musical instruments, or learning a script is designated by the term 'अभ्यास' (practice). Terms like 'कसरत' (exercise) and 'व्यायाम' (workout) apply exclusively to physical body conditioning. Therefore, Option B is syntax-wise pure.
