How can string be None? That doesn't make sense!

Wait, string[0] == 'o'? That sounds off.

I feel like string[-1] should be 'o' after the reassignment, but I'm not completely confident about the comparison with string[0].

I remember a practice question where we checked string lengths, but I can't recall if len(string) would be 3 here.

I think the string slicing part gives us 'pto', so I'm not sure if string[0] would be 'o' or something else.

I definitely remember that 'is None' checks for null values, but I don't think that's relevant here since string has a value now.

Option A seems like the most straightforward rule to me. Counting one FTR for each unique data function that is accessed makes the most sense.

I've got a good feeling about this. Autonomous agents that can monitor and repair themselves seem like a common use of self-healing tech. I'll go with D.
