The answer is YES: C will by installed twice. The first installation is under the node_modules folder. The second in npm v2 manner under a node_modules folder in the directory of the module depending on it.

There is a detailed explanation on npm.

Thanks! Any idea how it decides which one will be installed in v2 manner and which one in v3 manner?

It's the installation order. Let assume A depents on Cv1 and B on Cv2. If you run npm i A B Cv2 will be nested. If you run npm i B A Cv1 will be nested. The following both chapters of the above link will also cover this theme.
