Based on the table provided, the appropriate observation is:
Bhutan’s GNI exceeds the LDC threshold.
This is supported by the fact that Bhutan's per capita gross national income (GNI) is reported as US$2,982, which is greater than the LDC threshold of US$1,222. The other statements either do not have enough information to confirm their accuracy or are not directly supported by the data in the table.
