खाली दोन विधाने आहेत. त्यापैकी (अ) हे विधान असून (र) हे त्याचे कारण आहे खालील दिलेल्या पर्यायांपैकी योग्य पर्याय निवडा. विधान (अ) : विषुववृत्तीय प्रदेशामध्ये सागराची क्षारता कमी असते. कारण (र) : विषुववृत्तीय प्रदेश हा अति पर्जन्यमान, आभाच्छादित आकाश आणि आर्द्रता ही वैशिष्ट्ये असलेला आहे. Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R). Select your answer from the following options. Assertion (A) : Oceanic salinity is low in the equatorial region. Reason (R) : Equatorial region is characterized by heavy rainfall, cloudiness and humidity.
High rainfall in the equatorial region brings freshwater, which dilutes the ocean water and lowers its salinity, making both the assertion and reason true and properly linked.
