Correct option is C
Option (c) is the correct order of the given sentence.
• The sentence must start with the subject, so “intoxicating drinks” (b) comes first.
• Next, we need the verb phrase that tells what they are, so “are bad for health” (a) follows.
• Then we add the additional idea using a conjunction, so “and should be avoided” (d) comes next.
• Finally, “at all costs” (c) fits best at the end as it acts like an adverbial phrase showing strong emphasis.
Correct sentence formed: Intoxicating drinks are bad for health and should be avoided at all costs.
