(单选题)

What can be inferred from the third paragraph? ( ).

A.The traditional social networks will have great impact on certain groups.

B.The private messaging apps will replace the social media apps.

C.The intimate channels can be the double-edged swords to the sellers.

D.The growth of the intimate channels will bring only benefits to the marketers.

参考答案：C

参考解析：

从最后一段The rise of more intimate channels presents new opportunities, and perhaps perils, for marketers.可以得知新型熟人型的软件会带来新机会，同样也给市场开发者带来问题，perils这个词是关键，转换话锋。C项说明它作为双刃剑给销售者恰是这个道理。A传统的社交媒体会对某些群体产生巨大影响，和原文不符，B私人信息APP将会代替社会传统APP，不符原文。D出现绝对词only，可排除。故本题正确答案选C。
