Select the combination of letters that when sequentially placed in the blanks of the given series will complete the series.
P _ A A _ _ Z A _V _ _ A _ _

P _ A A _ _ Z A _V _ _ A _ _

Concept: (PZAAV) repetition of this letter cluster.

Explanation: To fill the series, we have to divide the series – P _ A A _ / _ Z A _V / _ _ A _ _

Let's check each option –

(a) VPZZPVAP; P V A A P / Z Z A Z V /PV A AP (No repetitive pattern is followed)

(b) ZPVVAPVZ; P Z A A P / V Z A V V / AP A VZ (No repetitive pattern is followed)

(c) ZVPAPZAV; P Z A A V /P Z A A V / PZ A AV (PZAAV is repeated)

(d) VZAAPVPZ; P V A A Z / A Z A A V / PV A PZ (No repetitive pattern is followed)

So, the correct answer is ZVPAPZAV.

Thus, the correct option is (c).
