问题如下：
The emerging marketcountry is more likely to engage in sterilizedintervention if its:
选项：
A. inflation rate ishigh
B. currency isundervalued
C. currency appreciationis caused by push factors rather than pull factors
解释：
Acountry would likely choose sterilized intervention if it had a highinflationrate, because unsterilized intervention would add to the monetary baseandpossibly increase inflationary pressures. B is incorrect because anundervalued currencyis likely to lessen the probability of intervention,sterilized or unsterilized, in response tocapital inflows. C is incorrectbecause both push and pull factors can lead to bubbleconditions, excessiveexchange rate appreciation, and the unwanted build-up ofexcessive speculativepositions.
解析：如果一个国家的通胀率很高，它很可能会选择冲销干预，因为未冲销干预会增加货币供给量，从而增加通胀压力。A正确。
B是不正确的，因为被低估的货币可能会降低干预的效用，无论是冲销的还是未冲销的干预。
C是不正确的，因为push以及pull因素都可能导致泡沫状况、汇率过度升值，以及不必要的过度投机仓位。
