问题如下：
Two examples of pricing models for complex products are ____________, which refers to incentivizing or requiring the purchase of multiple products or services, and ____________, which combines a low price on an initial purchase of a durable good with high-margin prices on associated consumables.
选项：
A.
bundling; razor, razorblade
B.
fractional ownership; subscriptions
C.
horizontal integration; network effects
解释：
A is correct.
Companies often bundle complementary products and services by offering a discount for their combined purchase versus the sum of the individual prices, such as a product and a repair/maintenance package. A razor, razorblade model, named for Gillette’s business model of selling a razor with disposable razorblades, combines a durable good sold at near cost with high-margin, possibly proprietary consumables needed to use the durable good. Other examples include Nespresso and Keurig coffee machines, printers and toner/ink, and diagnostic instruments and reagents.
虽然做对了，但是对每个选项的单词意思不是很清晰，能不能解释一下名词，谢谢
