Answer:
Debit retained earnings for $15.30 million.
Explanation:
As per the data given in the question,
Declaration of common stock dividend indicates no cash payments, only extra shares issued with rate of stock dividend
In this Rick Co. had 30 million shares and Rick Co. declared 1% stock dividend  
which means 30 million × 1% = 0.30 million shares issued
Retained earning = (0.30 million × $51)  
= $15.30 million
 To common stock A/c =  (0.30 × $1) = $0.30 million
To capital paid in access A/c = (0.30 million × ($51-$1)) =  $15.00 million
( Being stock dividend was issued at 1% )
Hence, Option (d) Debit retained earning for $15.30 million is correct.
