Step 1: Background of the play.
Girish Karnad's Hayavadana (1971) is one of the landmarks of modern Indian theatre. It combines folk theatre techniques with myth and modern philosophy.
Step 2: Trace the sources. \begin{itemize} \item Somadeva's Kathasaritsagara: Contains the original Sanskrit tale of "The Transposed Heads," where two men's heads are interchanged, raising philosophical questions of identity and body-soul dualism. \item Thomas Mann's The Transposed Heads (1940): A novella based on the same Sanskrit tale; Karnad explicitly acknowledged its influence. \end{itemize}
Step 3: Rule out other options. - Valmiki's Ramayana: A classical epic but unrelated to Hayavadana. - Franz Kafka's The Metamorphosis: Also deals with transformation, but thematically unrelated to Karnad's sources. \[ \boxed{\text{Correct Answer: (A) and (C)}} \]

A stick of length one meter is broken at two locations at distances of \( b_1 \) and \( b_2 \) from the origin (0), as shown in the figure. Note that \( 0<b_1<b_2<1 \). Which one of the following is NOT a necessary condition for forming a triangle using the three pieces?
Note: All lengths are in meter. The figure shown is representative.

Here are two analogous groups, Group-I and Group-II, that list words in their decreasing order of intensity. Identify the missing word in Group-II.
