Select the phrase/connector (it must be at the start) from the given three options which can be used to form a single sentence from the two sentences/phrases given below, implying the same meaning as expressed in the sentences.
I. The radar is also linked to an alarm system.
II. It enables automatic control and warning measures in case an avalanche is triggered.
i) As ii) Since iii) Eventually

The sentences individually talk about the radar and automatic control and warning measures. The first sentence mentions that the radar is linked to an alarm system, and the second sentence mentions the result/use of radar being linked to the alarm. So, the linking words which may be used should connect the sentences in a way that the first sentence is the reason why the radar is able to enable automatic control and warning measures. 'As' and 'since' go before the reason. When they are at the beginning of the sentence, we put a comma in the middle to separate the clauses. So, the sentence formed would be: As/since the radar is also linked to an alarm system, it enables automatic control and warning measures in case an avalanche is triggered. 'Eventually' is not used before the clause which gives the reason. So, Only i and ii are correct. Hence, option (c) is the answer.
