Solution:
Both (A) and (R) are true and (R) is the correct explanation of (A).Kerala has a low infant mortality rate because the state's fundamental healthcare and educational resources are sufficient and well-maintained. In this case, the reason is the proper justification for the statement, and both the assertion and the reason are true. The infant mortality rate (IMR), which is expressed as a percentage of 1000 live infants born in a given year, shows the number of infants who pass away before turning one. When the government assumes responsibility for supplying adequate healthcare services and enhancing cleanliness, the incidence of child fatalities will inevitably decline. Low infant mortality is a sign of effective government.
