Concept: Gender inequality affects disaster vulnerability. In many societies, women may have less access to information, mobility, resources, and decision-making power.
Step 1: Checking Assertion (A).
In gender-biased societies, unequal access to disaster-related information can make women more vulnerable during disasters. This is because timely warning and information are very important for safety.
\[
\text{Less access to information} \Rightarrow \text{Higher vulnerability}
\]
So Assertion (A) is correct.
Step 2: Checking Reason (R).
Men often have wider social and spatial networks in gender-biased societies. This means they may receive warnings, news, and outside information faster.
\[
\text{Larger networks} \Rightarrow \text{Better access to information}
\]
So Reason (R) is also correct.
Step 3: Checking explanation.
Reason (R) explains Assertion (A) because larger male networks can create unequal access to disaster information, increasing women's vulnerability.
Therefore, both Assertion and Reason are correct and Reason is the correct explanation.
