• D. $\{x:x$ is the tallest member of parliament $\}$

Answer 1

Answer: (B), (D)

The correct options are
B The collection of students in Bangalore
D $\{x:x$ is the tallest member of parliament $\}$

$\left(a\right)$ Biggest-adjective, so not a set
$\left(b\right)$ Clearly it is a set as it is well defined collection
$\left(c\right)$ small-adjective, so not a set
$\left(d\right)$ Clearly it is a set as it is well defined collection (only one element)
