This question is missing the options. I've found the complete question online. It is the following:

What type of common political behavior involves creating obligations, developing alliances, and using them to accomplish objectives? select one:

a. reciprocity.

b. coalitions.

c. alliances

d. networking

The type of political behavior described is:

a. reciprocity.

Explanation:

When it comes to politics, not only internal but also international, reciprocity is the behavior that leads to mutual benefits. Upon doing something, a party or a country, for instance, expects the other party or country to also do something. If an agreement or alliance is made, all who are involved are expected to act in order to make sure everyone's goals and/or the common goals are accomplished. A sense of obligation is built toward one another.
