How many countries can be selected to meet only condition 1?
Explanation:
If only condition 1 is imposed then we can select,
USA-UAE and USA-UAE-UK.
So, we have two combination.
Hence, option (b). Note: This question is ambiguous, as it is asking number of countries. In that case, we can select 2 or 3 countries. But we don't have options. So here we are assuming number of different combinations are asked.
