The question is asking about the purpose of a five million dollar grant that was provided by India to Tajikistan in the year 2001.
Option 1 says it was to "tackle the drought situation". This is the correct answer, implying that the financial aid provided by India was meant to help Tajikistan in managing a drought situation they were facing at that time.
Option 2 suggests the money was to "set up a software Technology Park". This option is not correct because the funds were not intended for technology or infrastructure development.
Option 3 implies that the grant was offered to "promote mineral exploration". However, there is no record of this assistance being tied to mineral resources or exploration.
Option 4 states it was to "procure defence equipment". As per available data, there`s no indication that the grant was intended for defence sector or procurement of equipment.
In summary, option 1 is the correct answer with the assumption that the money was provided to assist Tajikistan in overcoming a severe drought they were dealing with in 2001.
