Answer:
b. should be slower in a country that has to engage in the creation of new technologies and faster in countries that get to deploy technologies that have already been created elsewhere.
Explanation:
The previous excerpt does imply that in the end, growth is slower in countries that engage in the creation of pioneering technologies, rather than the countries who just adopt a technology that has already gained traction elsewhere.
Although the capability of the country to create such a technology implies heavy growth, it is not the case. Growth is measured through the function of time, and since it took a lot of time and resources for advanced countries to produce such technologies, growth isn't that high (despite the outcome of the technology). But, when a low-income country simply adopts the technology, growth exponentially rises.
