JEE Math Practice Question

Two sets A and B are as under : A = {($$a$$, b) $$ \in $$ R $$ \times $$ R : |$$a$$ - 5| < 1 and |b - 5| < 1}; B = {($$a$$, b) $$ \in $$ R $$ \times $$ R : 4($$a$$ - 6)2 + 9(b - 5)2 $$ \le $$ 36 }; Then

1. A.neither A $$ \subset $$ B nor B $$ \subset $$ A
2. B.B $$ \subset $$ A
3. C.A $$ \subset $$ B
4. D.A $$ \cap $$ B = $$\phi $$ ( an empty set )
