Correct option is A
Neither conclusion (I) nor (II) follows. From the given statements, we only know that "some mountains are ants" and "all elephants are ants." There is no information that directly connects elephants to mountains or gives us a definite relation between all ants and mountains. Hence, both conclusions are invalid as they make assumptions beyond the provided data.
· (a) Neither conclusion (I) nor (II) follows: ✔ Correct; both conclusions go beyond the data.
· (b) Only conclusion (I) follows: ✘ No connection is provided between elephants and mountains.
· (c) Only conclusion (II) follows: ✘ The statement "some ants are not mountains" cannot be concluded definitively from the given data.
· (d) Both conclusions (I) and (II) follow: ✘ Both are incorrect based on the logical rules.
