A word given in bold is followed by I, II and III, each of which consists of two sentences. You need to identify the options where the given word can be used as a connector to combine the two statements into a single one while maintaining the meaning and coherence of the sentence. However
I. Using the highly sophisticated technology of radio telemetry, officials can get real-time information about tiger’s movement. If a non-collared tiger has to be captured, wildlife managers have to depend on the traditional methods of following pugmarks, tiger scats, scratch marks on trees, and camera traps.
II. Wrong census figures can be attributed to lax attitude. Officials are hardly interested in working in the fields, and the method leaves a lot of scope for fudging, as its rate of error is very high.
III. AI-powered tools are built on huge amounts of data that is only accessible by big companies, making it easier for them to devise automatic speech recognition systems. Data privacy could be a significant challenge in an industry dominated by few tech moguls.

(c) However:  used to introduce a statement that contrasts with or seems to contradict something that has been said previously. The first statement in pair I mentions about radio telemetry technology used for getting real-time information about tiger’s movement. In contrast, the second statement is about techniques used to capture non-collared tigers. This presents a contrast and ‘however’ can be used to connect the sentences. The first statement in pair II mentions about the lax attitude of officials and the second sentence talks about the disinterest of the officials of working in the fields. So, there is no contradiction between the two statements. Hence, ‘however’ cannot be used. The first statement in pair III mentions about how big companies use huge amounts of data to build AI-powered tools to devise automatic speech recognition systems. The second statement says that as the data is used by only few tech giants keeping privacy can be difficult. This presents a contrast and ‘however’ can be used to connect the sentences. Hence, option C is the correct choice.
