选项：

A.

Centralization in the DeFi ecosystem is non-existent.

B.

Decisions in the DeFi ecosystem are made through a fully decentralized process.

C.

D.

解释：

The use of governance tokens and oracles, among other factors, has led to increasing centralization in the DeFi ecosystem. Therefore, option C is the correct answer. Option A is incorrect because the passage explicitly describes several examples of centralization in the DeFi ecosystem. Option B is incorrect because the passage describes how decisions in the DeFi ecosystem are often made through a voting process that involves governance tokens, which are often heavily concentrated. Option D is incorrect because the passage describes how centralization exists in several areas of the DeFi ecosystem, not just in trading activities.
