Answer:
I think the answer is D. Your ability to inspire, encourage, and be kind to others.
Step-by-step explanation:
I chose this answer because your "spark" should be something uplifting that keeps you going in life, keeping you humble.
A, B & C all have a negative impact although it may be slight.
A-lying doesn't spark your joy it makes you feel guilty
B-causing anger upon someone else has no benefit to either of you
C-you could be speaking a hurtful truth to someone that causes sadness
D-inspiring, encouraging, and kindness are all signs of happiness and give both people a feeling of warm-heartedness
