Correct Option : A
Explanation:
"'Had rather', 'had better', 'had sooner', 'had as soon....as...' are used with bare infinitives.
For e.g.
a)- He had better go(bare inf.) now.
b)- He had as soon run(bare inf.) as walk(bare inf.)."
Common mistake
-
We don’t use had rather or had sooner with an -ing form or a to-infinitive
