This is another Assertion-Reason question, this time about individual differences in athletes' behaviour. The safest way to answer these is to check A and R independently first, then decide whether R accounts for A, and finally match that against the four combination options.
- Option 1 (Both true, R explains A): Two athletes reacting differently in the same match situation, one staying composed under pressure while another reacts impulsively, is a routinely observed fact in sport, so A is true. Personality being the sum of a person's thoughts, traits, behaviour, attitude and habits is the standard definition used in sports psychology, so R is also true. Since differing actions and responses in A are direct manifestations of the behaviour and characteristics described in R, R does explain why A happens. This option fits.
- Option 2 (Both true, R doesn't explain A): This would apply only if R were a true but disconnected fact. Here, though, R's components are the very things that produce the differing actions and responses named in A, so the link is direct, not incidental.
- Option 3 (A true, R false): This would require the definition of personality in R to be wrong. Personality being a composite of thoughts, characteristics, behaviour, attitude and habits is an accepted, standard definition, not a false claim, so this option fails.
- Option 4 (A false, R true): This would require it to be false that two athletes respond differently in a match. In practice, individual variation in competitive behaviour is well documented and easily observed, so A cannot be dismissed as false.
Only the first option is consistent with both statements being factually correct and logically connected.
Therefore, the correct answer is Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of the Assertion (A).
