Answer:
C
Step-by-step explanation:
In a right issue , an existing share is entitled to a right , therefore 5,000,000 existing share has 5,000,000 rights and 500 shares has 500 rights
New shares are issued in proportion to the right held by each shareholder
To buy 1000000 share , 5000000 rights are required
for an extra share ( 5000000/1000000) 5 rights required
500 shares with 500 right can buy 500/5 shares =100 shares
