in the case "C" the two numbers are 19 and 1 but in this 19 and 1 are prime and their sum is 20 but their LCM is not 99 and 1 is neither a prime nor composite in the remaining cases there will be atleast one composite number

prime to each other means the numbers has to be co prime i.e, both number should have common factor 1
so a) and b) cannot be the answers since
option a) has common factor 4 and
b) has common factor 2
so option c) and d) are left
lcm of option c) and d) are 19 & 99 respectively
so final answer which satisfy both the conditions is option d) 11& 9
