Answer 1

The correct option is C $M\times K-T$

From options
(a) M + K + T
$=M\stackrel{Sister}{\leftarrow }K\stackrel{Father}{\leftarrow }T$
M is the aunt of T.
$\left(b\right)M\times K+T$
$=M\stackrel{Brother}{\leftarrow }K\stackrel{Father}{\leftarrow }$
M is the uncle of T.
$\left(c\right)M\times K-T=M\stackrel{Brother}{\leftarrow }K\stackrel{Mother}{\leftarrow }T$
M is the maternal uncle of T.
(d)M + K -T
$=M\stackrel{Sister}{\leftarrow }K\stackrel{Mother}{\leftarrow }T$
M is the aunt of T.
So, option (c) gives the stated relation.
