Two Statements are given followed by two Conclusions:

Statements:
All cats are dogs.
All cats are black.

Conclusion-I: All dogs are black.
Conclusion-II: Some dogs are not black.

Which of the above Conclusions logically follows/follow from the two given Statements, disregarding commonly known facts?

Correct Option: (c) Neither Conclusion-I nor Conclusion-II

Given statements: 1. All cats are dogs. 2. All cats are black. Let us analyze using Venn diagrams or set theory. Let C = Cats, D = Dogs, B = Black things. From statement 1, C is a subset of D. From statement 2, C is a subset of B. Conclusion-I: All dogs are black. Since only cats are known to be dogs and black, we cannot conclude that all dogs are black (there could be dogs that are not cats and not black). Thus, Conclusion-I does not follow. Conclusion-II: Some dogs are not black. While it is possible, it is not definitively established as a universal logical certainty from the given affirmative premises (as all dogs might theoretically be black in a degenerate case, though unlikely in standard syllogism unless proven). Wait, in standard categorical syllogism, from two affirmative universal premises ('All C are D', 'All C are B'), no negative conclusion like 'Some dogs are not black' can ever follow. Therefore, neither Conclusion-I nor Conclusion-II logically follows.
