Option C, no doubt. Don't want the delivery guy charging extra 'cause someone changed the multiplier, am I right?

Option D is just asking to be changed accidentally. Gotta go with C to keep that value locked down.

Hmm, I'm not sure. Option B seems more explicit about it being a constant, but Option C also looks valid.

I'm not sure, but I think B) constant decimal DELIVERY_MULTIPLIER = 4.15; could also work.

I'm going with Option A. 'static' is enough to make the variable a class-level constant that won't change.

Option C looks good to me. The 'static final' keyword makes the constant immutable and accessible across the class.

I agree with Gracia. Using static final ensures the value won't change.
