Complete answer: In the given question, we have to find out which of the options given to us indicates a tendency or disposition to drink.
Let us thus analyze the options given to us in this question:
Option (a), 'adequate', refers to ‘(obsolete) to equalize; to make adequate.’
Therefore, option (a) is incorrect as it does not indicate a tendency or disposition to drink.

Option (b), ‘apt', refers to ‘(usually followed by `to') naturally disposed toward.’
Therefore, option (b) is correct as it indicates a tendency or disposition to drink.

Option (c), ‘common', refers to ‘belonging to or participated in by a community as a whole; public.’
Therefore, option (c) is incorrect as it does not indicate a tendency or disposition to drink.

Option (d), ‘probable', refers to ‘likely but not certain to be or become true or real.’
Therefore, option (d) is incorrect as it does not indicate a tendency or disposition to drink.

Option (e), ‘suitable', refers to ‘meant or adapted for an occasion or use.’
Therefore, option (e) is incorrect as it does not indicate a tendency or disposition to drink.
