For the clock shown in the figure, if

$$ \begin{aligned} & O^*=O Q S Z P R T, \text { and } \\ & X^*=X Z P W Y O Q, \end{aligned} $$

then which one among the given options is most appropriate for $\mathrm{P}^*$ ?

Consider a five-digit number PQRST that has distinct digits P, Q, R, S and T, and satisfies the following conditions:

$$ \begin{aligned} & P < Q \\ & S > P > T \\ & R < T \end{aligned} $$

If integers 1 through 5 are used to construct such a number, the value of $P$ is:

A color model is shown in the figure with color codes: Yellow (Y), Magenta (M), Cyan (Cy), Red (R), Blue (BI), Green (G), and Black (K).

Which one of the following options displays the color codes that are consistent with the color model?

An object is said to have an n-fold rotational symmetry if the object, rotated by an angle of $\frac{2 \pi}{n}$, is identical to the original.

Which one of the following objects exhibits 4-fold rotational symmetry about an axis perpendicular to the plane of the screen?
