Step 1: Map "going around the room".
Order of slots around the room: \(E_1,E_2,E_3,W_3,W_2,W_1\).
Placing \(\text{MOTHER}\) gives:
\(E_1=M,\ E_2=O,\ E_3=T,\ W_3=H,\ W_2=E,\ W_1=R\).
Step 2: Read opposites and adjacencies.
Opposites: \(E_1\leftrightarrow W_1: M\leftrightarrow R\),
\(E_2\leftrightarrow W_2: O\leftrightarrow E\),
\(E_3\leftrightarrow W_3: T\leftrightarrow H\).
Adjacencies (same wall): \(M\)–\(O\), \(O\)–\(T\) on east; \(R\)–\(E\), \(E\)–\(H\) on west.
Step 3: Test the options.
(a) \(O\) opposite \(E\): \textit{True}. \quad
(b) \(H\) next to \(E\): \textit{True}. \quad
(c) \(T\) next to \(O\): \textit{True}.
(d) \(T\) opposite \(R\): \textit{False} (since \(T\) is opposite \(H\)).
\[
\boxed{\text{(d)}}
