Step 1: Verify Statement 1 about NCDRC.
The National Consumer Disputes Redressal Commission (NCDRC) is indeed headquartered in New Delhi. Statement 1 is true.
Step 2: Verify Statement 2 about the consumer definition.
Under Section 2(7) of the Consumer Protection Act, 2019, a person who buys goods for resale or for any commercial purpose is explicitly excluded from the definition of "consumer." A person buying for resale is therefore not a consumer under the Act. Statement 2 is false.
Step 3: Determine the correct option.
Since only Statement 1 is true and Statement 2 is false, option (1) is correct.
\[ \boxed{\text{Only (1) is true}} \]
