A) \[A\cap B=\phi \] (an empty set)
B) neither \[A\subset B\] nor \[B\subset A\]
C) \[B\subset A\]
D) \[A\subset B\]
Correct Answer: D
Solution :
\[-1<a-5<1\] \[\Rightarrow a\in (4,6),b\in (4,6)\] \[\frac{{{(a-6)}^{2}}}{9}+\frac{{{(b-5)}^{2}}}{4}\le 1\] \[-3\le a-6\le 3\Rightarrow a\in (3,9)\] \[-2\le b-5\le 2\Rightarrow b\in (3,7)\]
