You want to create a route that handles URLs like '/product/123/review/456' and runs a function with both IDs. Which route definition is correct?
ARoute::get('/product/{productId}/review/{reviewId}', function ($productId, $reviewId) { return "Product $productId, Review $reviewId"; });
BRoute::get('/product/{productId}/review', function ($productId, $reviewId) { return "Product $productId, Review $reviewId"; });
CRoute::get('/product/review/{reviewId}', function ($productId, $reviewId) { return "Product $productId, Review $reviewId"; });
DRoute::get('/product/{productId}/review/{reviewId}', function () { return "Product $productId, Review $reviewId"; });
