Select the option that is related to the fifth letter-cluster in the same way as the second letter-cluster is related to the first letter-cluster and the fourth letter-cluster is related to the third letter-cluster.
ONGOING : HOIOHOO :: PROJECT : UDEKOSQ :: REPORTS : ?

Let's decode the shifting patterns for each word pair:
ONGOING -> HOIOHOO
Let's check letter-by-letter or in subsets:

Split into parts or reverse order + shifts:

Let's check positions:
O(15) N(14) G(7) O(15) I(9) N(14) G(7)
H(8) O(15) I(9) O(15) H(8) O(15) O(15)

Let's look at the reverse of ONGOING: G N I O G N O

G(7) + 1 = H(8)

N(14) + 1 = O(15)

I(9) + 0 = I(9)

O(15) + 0 = O(15)

G(7) + 1 = H(8)

N(14) + 1 = O(15)

O(15) + 0 = O(15)

Wait, let's look at vowels vs consonants in reverse order:

Consonants get +1, Vowels stay the same?

Let's check: Reverse of ONGOING is G, N, I, O, G, N, O

G (consonant) +1=H

N (consonant) +1=O

I (vowel) +0=I

O (vowel) +0=O

G (consonant) +1=H

N (consonant) +1=O

O (vowel) +0=O

Result: HOIOHOO. This pattern matches perfectly!

PROJECT -> UDEKOSQ

Reverse of PROJECT is T, C, E, J, O, R, P

Apply rule (Consonant +1, Vowel unchanged):

T (consonant) +1=U

C (consonant) +1=D

E (vowel) +0=E

J (consonant) +1=K

O (vowel) +0=O

R (consonant) +1=S

P (consonant) +1=Q

Result: UDEKOSQ. Matches perfectly!

REPORTS -> ?

Reverse of REPORTS is S, T, R, O, P, E, R

Apply rule:

S (consonant) +1=T

T (consonant) +1=U

R (consonant) +1=S

O (vowel) +0=O

P (consonant) +1=Q

E (vowel) +0=E

R (consonant) +1=S

Result: TUSOQES.
