Wait, why would you decrease intervals? That seems counterproductive.

A sounds risky, batching could lead to more issues.

I think C makes more sense, gives it time to recover.

I’m a bit confused about the differences between options B and C. I guess C is better because it increases the wait time, but I’m not 100% certain.

I think we practiced a similar question, and I chose option C then as well. It seems like the best approach for handling 503 errors based on what I recall.

I'm not entirely sure, but I feel like option B could work too since it mentions a set time interval, which might help avoid overwhelming the API.

I remember we discussed retry strategies in class, and I think option C makes sense because it uses exponential backoff, which is often recommended for handling transient errors.
